About the PUTM EV APPS 2021 PCB

PUTM EV APPS 2021 is an open source STM32 PCB design by PUT-Motorsport, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 100.7 × 63.5 mm, with 72 components from 32 distinct parts.

Its main chip is the STM32F103C8Tx, from the STM32 family. Other key parts include the LM2596S-5, LM1117-3.3, MCP2562-H-SN and MCP6001-OT. By type, the board carries 20 capacitors, 17 resistors, 14 diodes, 8 ICs, 6 connectors and 2 inductors.

It belongs with the sensors designs in this gallery.

From the project

FS APPS project

APPS handling is required by official FSG Rules according to T11.8 (see). APPS signals are system critical signals meaning that any implausibility between sensors or a failure should result in complete motor power shutdown.

0% - fully released 100% - fully applied

Implausibility is defined as a deviation of more than ten percentage points pedal travel between any of the used APPSs. If it occurs for more than 100 ms the power to the motor must be immediately shut down.
