Good news - we have a new solution to the international shipping issue, and the lowest cost international option now starts at $6!
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.
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. F version of this board, which adds back in the pads for an extra 1206 decoupling capacitor (though this is not necessary under typical conditions), while still including the PCG and PGD pins for reprogramming the internal PIC microcontroller. This version uses V-Groove panelization, so the boards are easy to separate and have smooth edges.
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!)
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.
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.
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.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I build projects with Arduino (ATtinies almost exclusively, never anything bigger than a '328p) and Espruino (often both working together), and I make a lot of circuit boards for these projects. Particularly after using my ATtiny-prototyping board for my own projects, I realized that these would be useful to other people, and decided to start selling them here on Tindie.
Strip Board, Protoboard, prototyping board, solderable breadboard - whatever you want to call it - it has been a mainstay in electronics prototyping for decades, and hasn't changed much in the interim (not even in production quality, as they're still often single-sided and/or manufactured from low-grade phenolic resin instead of FR4). My prototyping board creations bring these into the modern era, offering a combination of 0.1" through-hole prototyping areas (consisting of groups of 2, 3 or 4 pins connected together, like solderable breadboard) and pads for common surface mount packages connected to through-holes for easy soldering. To handle projects of all sizes, I offer prototyping board as large as 4" x 4", down to less than an inch square in my Mini Protoboard line. Unlike most commercial prototyping board, these boards are made to the same quality standards as real PCBs. Through-holes are plated, and the boards are double sided. These are offered in both generic versions, and ones tailored to specific microcontrollers, like the Tiny84/85, or microcontroller boards, like the Espruino Pico, Arduino Pro Mini, and the wildly popular ESP8266.
ATtiny breakout boards:
I love the ATtiny lineup, particularly some of the less popular ones, like the incredibly full-featured ATtiny841, ATtiny1634, and ATtiny828. Breakout boards for these that had the features I wanted were not readily available - so I made my own. I've since expanded my product line to include breakout boards for the ATtiny861, ATtiny167, and ATtiny88 - and all of these are available both as bare boards and assembled. In addition to designing the hardware I also maintain [ATtinyCore Universal](https://github.com/SpenceKonde/ATTinyCore), which enables Arduino support for all these ATtiny's and more.
I also sell a number of other boards to fill what I felt were gaps in the market, including a breakout board for the popular LoRa/LoRaWAN modules from Microchip (the RN2483 and 2903), which has become one of my top selling items. I also sell MOSFET drivers and breakout boards for logic level MOSFETs operating at logic levels of 2.5v and lower - while a great number of MOSFETs are available that operate with very low gate voltages, these are almost invariably SMD parts which are difficult to use without a properly designed breakout board.
