# 0xB2 - splinky
Pro-Micro/Elite-C replacement with USB-C and RP2040.
Designed for use in custom mechanical (split) keyboards, but many other uses are possible.
**This is a fork from the [0xb2 - splinky](https://github.com/plut0nium/0xB2) by plut0nium.**
**It uses a different usb-C port, which is similar to the one of the elite-C and will fit in the Bastardkb case designs.**
## Features:
* Pro-micro / Sparkfun RP2040 compatible footprint, with 5 extra pins at bottom (Elite-C style)
* Raspberry Pi RP2040 MCU
* Up to 16MB flash memory _(depending on component selection and availability)_
* User LED & USB VBUS detect
* Low profile USB-C mid-mount connector
* Designed to be manufactured and assembled by all common PCBA services (including JLCPCB)
## Pinout
The pinout is compatible with the widely available [SparkFun RP2040](https://www.sparkfun.com/products/18288), with extra GPIO12..16 pins broken out on the lower side.
USB VBUS detection on GPIO19.
> This pinout is a _de facto_ standard, established by actors of the MK community (see discussions in `#RP2040` on the bastardkb Discord server)
Additionnaly, a user LED is tied to GPIO17, can be used for UF2 bootloader status indication, or any other purpose (or turned OFF, no annoying always-on power LED).
## Programming
The splinky uses a basic two-button reset circuitry.
In order to put the board in bootloader mode, press briefly the RESET button (marked **R**) while holding the BOOT button (the second one).
If the buttons are not reachable (soldered upside down), the /RST pad can be shorted to GND, while the two smaller BOOT pads (next to D8) are maintained shorted (v2 only).
## Manufacturing
Releases contain required information (gerbers, bom, pos) for assembly by JLCPCB.
## Releases
* **v3** updated pinout - current release
* **v2** first public release
* **v1** first prototyping run
