Hardware Changelog
TJA1051 VIO
TJA1051 VIO uses 5V in v1.0/v1.1 — this will still work, but 3.3V is recommended.
-
v1.2 — Schematic
- Fix TJA1051 VIO to 3.3v
-
v1.1 — 2024-11-26 — Schematic
- Current Sample IC changed from INA169 to INA180B1 (mV/A unchanged, current offset fixed to 0mV)
- WS2812 LED moved to separate PCB
- HSE pad added to pin header
-
v1.0 — 2024-07-30 — Schematic
