Simple breakout board for RN2483/RN2903 LoRa transciever

This breakout board offers an affordable solution for makers working with the popular RN2483 and RN2903 LoRa transceivers from Microchip, widely used for LoRaWAN. The layout of this breakout board is based on the the datasheet reference designs. This board breaks out all 14 GPIO pins to a row of 0.1" pin header, and the power and serial communication pins to a second row of 0.1" pin header.

NEW Assembled Boards Available

The RN2483 and RN2903 are identical except for their transmission frequency and which world regions they are approved for use in. The RN2483 operates at 433mhz and 868mhz, and is approved for use in Europe, while The RN2903 operates at 915mhz, and is approved for use in the US, Canada, Australia, and New Zealand. The markings on these breakout boards correspond to the RN2483; if using with RN2903, use the antenna marked 868mhz (the low frequency antenna is not used).

The pin layout for the serial and power pins is designed such that it can be plugged into breadboard alongside an Espruino Pico, and the pins will line up - see the Espruino RN2483 module guide for details.

We are now shipping the Rev. E version of this board, which replaces the 1206 capacitor on the top of the board (which has been found to be unnecessary) with a pair of headers exposing pins 30 and 31 (PGC and PGD) to allow for reprogramming of the on-board PIC. This version also uses V-Groove panelization, so the boards are easy to separate and have smooth edges.

Bad-silkscreen buy-1-get-1-free sale

The second-most-recent version of the board, the Rev. D, shown below, is missing much of the silkscreen on the front (as shown in below image). The boards are otherwise fine, and the pin labels are present on the bottom. These boards are available buy-1-get-1-free while supply lasts! There's no coupon code - just choose to get the Rev. D version, and you'll get twice as many as you ordered for the same price. (Note - Buy-1-get-1-free only applies to the boards themselves, not optional level shifters!)

enter image description here

Optional Level Shifter

Since many of our customers are using these with 5v microcontrollers (such as Arduino), we now offer a level shifter as an add-on. These level shifters are mass produced 4-channel bidirectional fet-based level shifters. See the diagrams below for wiring examples.

Parts List

Required:

  • RN2483 (or RN2903, depending on your region)
  • 1x8 pin 0.1" pin header (or other connector) for power and serial connections.
  • 2 SMA antenna connectors, 1.6mm/0.063" board edge launch (Only one for the RN2903, SMA connector for 433mhz on RN2493 is optional, depending on your needs). Example SMA connectors include the Linx CONSMA003.062 (available from digikey) and Adafruit part no. 1865.

Optional:

  • 1117-series (or pin compatible) 3.3v voltage regulator in SOT-223 package. The ZLDO1117G33TA is suitable if powering from external 5~12V (as are many other 1117-series regulators). For operation off a single cell LiPo battery, a 1117-series is not sufficient (too much dropout), but the AP2114H-3.3TRG is suitable in these cases (it is no
  • 2 Capacitors (if using regulator) per regulator specifications, in 0805, 1206, 6032, or Kemet E package. For example, if using the ZLDO1117G33TA or AP2114H-3.3TRG regulator, a 4.7~22uF ceramic capacitor (X5R or X7R dielectric) is suitable for both input and output.
  • 1x2 pin 0.1" pin header for programming connections
  • 1x14 pin 0.1" pin header for GPIO connections

Don't forget prototyping board!

Bulk orders and Stencils

We typically have several hundred of these boards in stock. Tindie has a maximum purchase quantity of 99 boards; if you need more, message me immediately after ordering, or mention it in the order instructions, and I'll get in touch and make sure we can combine shipping.

The gerbers for the stencil (front and back) can be downloaded here: RN2483 Stencil

The boards are made in panels of 6 - if you order a multiple of 6 boards, you'll get full panels.

Why did you make it?

A number of Espruino users in Europe working with LoRaWAN requested an affordable, minimalist board design for use with the RN2483 modules. The design of these modules makes use without a purpose made breakout board virtually impossible, however, such boards were not available.

See this thread for additional background: http://forum.espruino.com/conversations/277687/

The break out board works Rev. C works very well for me.

It might be an idea to change the pinout of the serial interface in a future revision to be 1:1 compatible with FTDI cables to support even more easy prototyping.

Specify part numbers in parts list

- RN2483 breakout (bare board)
It would be helpful if the capacitor values were mentioned in the parts list. The datasheet is rather vague about actual values, saying only >= 4.7uF for the output capacitor, with a 0.05Ω ≤ ESR ≤ 0.5Ω rating. The input capacitor is even more vague: "Typically a large storage capacitor (0.05Ω ≤ ESR ≤ 0.5Ω) ...". For clarity, the 1206 is imperial, not metric.

The RF connectors are a real PITA to be sure you're ordering the correct ones the first time. There are a number of mounting styles for SMA connectors. This board needs a connector for a 0.062" thickness PCB, 0.1" between pins, in an "end launch" style. Having an actual part number would have saved a lot of time. BTW, the parts list says 2 SMA connectors are required, but actually only one is.

So how about adding some part numbers to parts list, please?

Thanks for the feedback, I've added the part numbers for two compatible SMA connectors that I've worked with (I know there are many others), as well as more specific suggestions for the capacitors for the regulators I recommend. That said, since the board is compatible with any of dozens of regulators available with a compatible pinout, I can't provide guidance for capacitor selection for all of the regulators that could be used - some of them are really picky about the regulator (hence the support for larger tantalum caps)

Well-built boards

- RN2483 breakout (bare board)
I'm relieved to have received my 2 well-boards in South Africa after 7 weeks' shipping. Good quality construction. I tied down the RN2483 using masking tape to solder it down, but after having soldered 2 pads, I lifted the masking tape, only to rip off one of the pads from the PCB - fortunately it was one of the ground pads. Other pads soldered without problems, except for a few shorts which I had to suck off to re-do. The second board should go better :-)

Edit: I received two Rev. C boards. One of the boards show pin labelled "NC" on the top and "RST" on the bottom (between the RTS and 3V3 pins). The photos here https://www.tindie.com/products/DrAzzy/rn2483-breakout-bare-board/ seem to show label "RST" on top of bottom of the boards, which are also labeled Rev. C...? My second board is labeled correctly...

Edit#2: second board successfully built, now I have 2 working mote's, yay!

Board to mount your RN2483 LORA module

- RN2483 breakout (bare board)
Neat board with provision for a voltage regulator and it has mounting holes! So many of the breakouts expect you to use a breadboard, fine for a prototype, but with a cased demo unit having a way to mount the board is essential. Modules soldered on with normal (fine) solder and fine tipped iron and I'd used liquid flux as well to ensure a good joint.

Please note in my ratings that there is in fact no paper documentation - so I've left the rating for the boards printed notation!

That's right - in order to ensure that documentation is always up to date, as well as to lower costs and reduce our impact on the environment, we do not include paper documentation. All documentation is available online linked to from this product page. If you have any questions, or find anything missing from the online documentation, please let me know and I'll get it fixed straight away.

nice boards

- RN2483 breakout (bare board)
I ordered 3 boards. They came in pretty quickly and are looking very nice. I like them a lot.

Soldered each of them, although I must admit that I'm no soldering king/ queen overall three pcb soldering patches got loose pretty easily. One of them was the 868 MHz antenna center patch... So now I'm left to soldering the antenna to the RN2483 directly.

Still a very nice pcb to order.

Hi - thanks for buying, and thanks for letting me know about your experience here

I just tried to reproduce pad lifting issues. I soldered a wire onto the pad, resting the soldering iron on the pad for far longer than usual (to simulate very poor soldering technique), and afterwards, I yanked pretty hard on the wire. I wasn't able to pull it off with any realistic amount of force.

Since you saw this on multiple boards, not just one, I'm inclined to suspect that your issue is largely one of equipment - namely your soldering iron. One of the easiest ways to lift pads is by using a soldering iron that's getting too hot (often because it's not temperature controlled). I tested this by cranking the temperature on my iron up to 850 (instead of 700) - and then, leaving the iron on the pad for a while, and then pulling on the wire, I was able to get the pad to pop off, which supports this theory. So - is your soldering iron temperature controlled? If not, I wager that's probably what caused the pads to lift. I recommend temperatures no higher than 700 when assembling boards (higher temps are great for salvaging parts from a board you don't care about).

Feel free to contact me (via messaging or email) if you have further questions on this.
