Mauch 002: PL-100 Sensor Board with CFK enclosure in India

The HS boards are based on the famous Allegra ACS758 hall current sensors, ACS758-050U for the 50A version, ACS758-100U for the 100A version and ACS758-200U for the 200A version. The electronic on the board is powered by an independent 4.0V LDO (LP2985-4.0) and the offset shifting is realized by an OP from Microchip (MCP601) specially designed for microprocessors analog inputs.
The sensor board is only installed into the “positive” (red) main wire from the LiPo, the “negative “black” wire stays untouched, which reduces the risk of short circuits on the sensor board.
The voltage measurement, has an installed filter which reduces the risk of false RTL trigger, which might be happened if we fly in very windy conditions due to sudden motor speed up to keep the flight leveled.
