# PolarBone
Placeholder for work on a Polarfire SoC based RISC-V BeagleBone compatible board
## Goals
* Provide a platform for developing fully open-source SoCs
* Provide solution for low-latency control, such as manufacturing machines
* Long-term availability for education
## Initial features in rank order of priority
* Microchip MPFS250T-FCVG484E RISC-V based Polarfire SoC with 250k logic elements
* BeagleBone AI compatible mechanical footprint, expansion headers, serial header, buttons, LEDs and microSD slot
* 2GB LPDDR4
* 16GB eMMC
* Gigabit Ethernet
* 2.4GHz WiFi/Bluetooth using ATWILC3000
* Sub-GHz transceiver using AT86RF212B
* TagConnect compatible JTAG header footprint
* USB Type-C with SuperSpeed/PCIe, able to provide power
* USB Type-A with SuperSpeed
* Low-speed flexible flat cable (FFC) expansion
* CANOpen 10-pin multipole connector, reserved signals brought to SoC
* MicroHDMI with ADI HDMI framer
* Additional power connector
