| 14 | +The 0xCB Helios is our Elite-C compatible MicroController, based on the high-performance and affordable RP2040. |
| 15 | + |
| 16 | +It's a drop-in replacement for legacy ProMicro boards. |

| 18 | +## Technical details |
| 19 | + |
| 20 | +- **Powerful RP2040** 32-bit Cortex M0+ dual core running at 133 MHz and 264kB SRAM. |
| 21 | +- **16MB/128Mb QSPI FLASH** chip for storing files and code |
| 22 | +- **Only 3.16 mm thick** thanks to a mid-mounted USB-C port |
| 23 | +- 3.3V 500mA LDO, PTC fuse and **ESD protection** chip |
| 24 | +- Elite-C, Pro Micro, SparkFun Pro Micro RP2040, and nice!Nano compatible pinout (follows the **BastardKb standard**) |
| 25 | +- **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) |
| 26 | +- **25 available digital pins** for a maximum of 13x12 = 156 switches (using a standard matrix) |
| 27 | +- Default off **red power LED** (selectable via a jumper on the left side) |
| 28 | +- **blue user LED** on pin GP17 |
| 29 | +- 4 pins configurable as **analog inputs** |
| 30 | +- **USB D+/D- broken out** for use with an external USB socket/daughterboard |
| 31 | +- **USB VBUS detection** on GPIO19 for split keyboard side detection |
| 32 | +- **UF2 bootloader** for drag & drop programming via your file manager |
| 33 | +- 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!) |
| 34 | +- **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. |
| 35 | +- **USB-C connector** lets you access built-in ROM USB bootloader and serial port debugging |
