Download and Install Raspberry Pi OS to SD card using Imager. Manually downloading the OS (zip-file), extracting the .img and using that seems to be more reliable than letting the Imager download the OS. https://www.raspberrypi.org/downloads/ Enable SSH Server: For headless setup, SSH can be enabled by placing a file named ssh, without any extension, onto the boot…
These H-Bridge modules have an issue with FET shoot-through at high (but <100%) duty cycles. The observations indicate it needs at least 2.9µs low signal before turning on again. 100% duty cycle again is fine too, since there’s no continuous switching happening which could cause repeated shoot-through, destroying the FET. It’s the area between zero…

Install „Bolder Flight Systems SBUS“ Library in Arduino Library Manager Connect to ELRS Receiver via WiFi and enable „Inverted SBUS“ as the Serial Interface. Select RX and TX pins and save. Hook up the UART TX pin of the ELRS receiver to a UART RX pin on the Arduino. Bind and connect ELRS receiver to…
We want to control rotational speed [n] in rpm, which is proportional to back-emf [e] in V. They are related via the motor constant [Kv] in rpm/V. Unfortunately, we actually can’t directly control e, since the motor windings, brushes, leads, and also our H-Bridge MosFETs add inductance L and resistance R to the circuit. We’ll…
