mcu 176 0.1

TC2030 on-board

Supply Input

5v

Supply Output

5v for analog sensors based on LC-filtered 5v input. This way we isolate op-amp power supply from sensor and etc noises.

🛑 NOT protected against grounding

🛑 NOT protected against +12 back-feed

Random note: mcu 144 v0.5 has approximately 6 totally unused/not connected stm32 GPIO pins (this has changed with rev 0.7)

mcu 176 v0.5 has approximately 16 totally unused/not connected stm32 GPIO pins
