5-Key + 1 Rotary Encoder Programmable Macro Keyboard for Arduino Pro Micro (32u4)

What is it?

Selling PCB ONLY. A PCB for an 6-key, hot-key, shortcut, stream-deck, or macro keyboard built using the off-the-shelf Arduino Pro Micro.

Standard configuration is 6 function keys + 1 mode key ( + 2 optional keys expanded with TRS jack). This PCB can be populated with up to 5 Cherry MX Keys and 1 rotary encoders (or omit the encoders for 6 keys). An additional 2 key breakout board can be used (with a TRS cable) to locate 2 cherry keys in discrete location (like a foot pedal). This PCB will fit either the Arduino Pro Micro with a micro USB or mini USB connector (the mini USB version has a slightly wider footprint).

Why did you make it?

I wanted to make a macro keyboard to improve my workflow with some CAD programs. A focus on backwards compatibility utilizing cheaper components and versatility was key so many USB input devices can be made cheaply. You can populate the board with a mix of rotary encoders, Cherry keys, or tactile switches. This keyboard was a built for hot-key Retropie commands in Raspberry Pi arcades.

What makes it special?

This is a mini version of a slightly larger macro keyboard https://www.tindie.com/products/19957/. I added some of my favorite ideas from other's creations like: a rotary encoder, a mode button to switch between custom key profiles, 3.5mm stereo jack breakout for external breakout (like a foot pedal), and addressable LEDs. Also on this PCB is an I2C breakout to easily add an LCD. The I2C has a solder jumper to select your voltage; USB 5V or the ProMicro's 3.3V. DO NOT solder both I2C Power Jumpers. The I2C connector has a configurable pinout via the solder jumpers. You can pick the PWR/GND and SDA/SCL order so most OLED LCDs can be soldered (or socketed) directly to this board. Some cool uses: macro keyboard for your PC or RPi, axis jog control for CNC machine, auto demo timer(attract mode) for arcade machines. Please see the YouTube video (coming soon-ish) for a complete explanation.

Great DIY Macro Keyboard

This macro keyboard was well designed and easy to setup. It doesn't have all the bell and whistles compared to it's the larger one: 3d printed case files, plate for soldering and multiple code examples. I've used it a few times now and it works great. Soldering the components was really easy and the labeling is really helpful. I would totally get this again. I do wish there was QMK firmware available but not sure if that is feasible.

Excellent Board

Had been looking to make a macro keyboard for work and ended up stumbling on Ryan's video. The documentation available on his website and instructions on the video are excellent. The 3d printable frame is so useful for keeping the keys square during soldering. Ordering some more for home and requests from friends.

The amount of time this saved me is well worth the cost of the pcb.

Excellent value for the price

This is a great way to get involved in keyboard building. The price is great. Documentation is excellent. Demo program actually runs perfectly. You can use Cherry MX keys or some cheaper varieties. I got my Arduino pro micros on ebay for less than $2 each. I wish that the board supported standard through hole components as well, but it does not. Even so, the smt components are not crowded and I had little difficulty (besides my old-man eyes) in soldering them to the board. Arrow electronics has everything in stock and they're great with low quantities. I have the larger version of this board and it is also excellent. Would buy either again. And probably will.
