Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the BTN9960LVAUMA1, INA180A2IDBVT, R-78E3.3-0.5 and AP7333-33SRG-7. By type, the board carries 36 capacitors, 30 resistors, 6 ICs, 6 connectors, 4 fuses and 3 diodes.
From the project
Bug Wiper Controller for Sailplanes Version 2 with ESP32-S3
The new version of the BugWiper system is a complete redesign of the hardware and software to improve the performance, reliability and features of the system. The new design is based on the ESP32-S3 micro controller. The new design also includes a new motor with higher torque, a self locking gear and a motor encoder to measure the motor position and speed. The new design also includes a new software architecture that allows for more advanced features like programmable cable length, soft direction change of the motor at the wingtip, slow down the motor before reaching the fuselage and logging…
