Elite-Pi Usage Guide

The Elite-Pi is an RP2040-based controller with a Pro Micro/Elite-C compatible pinout that's primarily intended for use with keyboards.
You can purchase them at your favorite keyboard store:
Microcontroller: RP2040
Flash Memory: 16Mbit (W25Q16JVUXIQ)
Pinout: Pro Micro-compatible
Number of available pins: Up to 25 I/O pins
Firmware Support: , ,
Mid-mount USB-C to keep low-profile
Availability:
In comparison to the Pro Micro or Elite-C, the Elite-Pi provides a few advantages over them:
Flash memory: Lots of space to compile in various QMK features without worry, as the Elite-Pi has much more flash memory
Price: Since the RP2040 microcontroller costs less than the ATmega32u4, we can provide it at a lower price than the Elite-C
Flashing: Instead of using QMK Toolbox, you can just copy a complied .uf2 file to the Elite-Pi to update the firmware
Converters
Examples:
Using QMK CLI:
Using make:
Without Converter
In the future, we plan on reducing the Elite-Pi to have just one button to perform Run and Boot.
To repeat the information there, here's the steps:
Enter bootloader mode (use one of the following methods):
For a new Elite-Pi out of the packaging, it will already start in bootloader mode when plugged into the computer
Double-tap the Run/Reset button (if flashed and was compiled with RP2040_BOOTLOADER_DOUBLE_TAP_RESET option)
Hold the Boot button (the left button) down, press the Run button (the right button), and release both buttons
Hold the Boot button (the left button) down, while pluging in the USB-C cable
Press the QK_BOOT keycode (if present on a flashed keyboard)
Wait for OS to detect the Elite-Pi
It will show up as a USB mass-storage device named RPI-RP2
Copy the .uf2 file to the RPI-RP2 USB drive
If you have the Elite-Pi installed with the back facing towards you, and you need to press Boot, take a wire and connect the Boot pad on the back and a GND pad, as shown below:
No, you can not mix the Elite-Pi with a non-RP2040 controller like the Pro Micro or Elite-C.
However, another RP2040 controller can be used with it.
If you would like to access D10 and/or D11 via the pads on the side of the Elite-Pi, you will need to cut the traces connecting GND to the those pads, as by default, the side pads are connected to GND to match the normal Pro Micro pinout. After cutting the traces, add solder as shown below to jump D10/D11.
The recommended way to use the Elite-Pi is using a converter in QMK. Note that you will not be able to take a .hex file compiled for a Pro Micro (ATmega32u4) and rename it as a .uf2 file, it just doesn't work that way. In either usage case, you will need a .
If you are using the Elite-Pi on a Pro Micro-compatible board, then you can use a in QMK to map the pins correctly to the PCB.
To use the converter, see the instructions here:
Alternatively, if you are creating a keyboard from scratch, you can use it as a RP2040 board as described here: .
At the moment with V1 of the Elite-Pi, there are two buttons on it for Run/Reset and Boot, unlike the Elite-C, where there is only one button needed for Reset. The left button is for Boot, and the right button is for Run. You will mainly be interested in getting the Elite-Pi into bootloader mode, so please see the for doing this.
The directions to flash the Elite-Pi can be found in the .
If you used the mentioned above, it will have this option enabled
The Elite-Pi can be used with CircuitPython, and since the hardware is the same as that of the Raspberry Pi Pico, you can use CircuitPython build for it:
