Update
As STM32F303CCT6 and STM32F405RGT6 are in shortage. ASPD-DLVR has been updated with L431 CAN node since Mar.2022. L431 version has identical PCB size(purple PCB) and layout to previous F405 version.
- Black PCB, F303 CAN node, Jul.2020 — Dec.2020
- Blue PCB, F405 CAN node, Jan.2021 — Feb.2022
