+The 0xCB Helios is our Elite-C compatible MicroController, based on the high-performance and affordable RP2040.
+
+It's a drop-in replacement for legacy ProMicro boards.
+
+## Technical details
+
+- **Powerful RP2040** 32-bit Cortex M0+ dual core running at 133 MHz and 264kB SRAM.
+- **16MB/128Mb QSPI FLASH** chip for storing files and code
+- **Only 3.16 mm thick** thanks to a mid-mounted USB-C port
+- 3.3V 500mA LDO, PTC fuse and **ESD protection** chip
+- Elite-C, Pro Micro, SparkFun Pro Micro RP2040, and nice!Nano compatible pinout (follows the **BastardKb standard**)
+- **8 extra I/O pins**: (GP12-GP16) added along the bottom edge, (GP10-GP11) at the top and a 5V level shifted pin to drive RGB LEDs for example (GP25)
+- **25 available digital pins** for a maximum of 13x12 = 156 switches (using a standard matrix)
+- Default off **red power LED** (selectable via a jumper on the left side)
+- **blue user LED** on pin GP17
+- 4 pins configurable as **analog inputs**
+- **USB D+/D- broken out** for use with an external USB socket/daughterboard
+- **USB VBUS detection** on GPIO19 for split keyboard side detection
+- **UF2 bootloader** for drag & drop programming via your file manager
+- easy to use and backward compatible **Single button boot and reset circuit** push to reset and hold >500ms to enter bootloader (legacy boards with reset buttons will continue to work!)
+- **RAW / VBUS** output, for powering RGB LEDs or other 5 V devices. The jumper on top lets you skip over the 500 mA fuse and Schottky diode, for up to 3A from USB ports.
+- **USB-C connector** lets you access built-in ROM USB bootloader and serial port debugging
