At the current moment, the SX1281 (RF IC) and ESP8285 (central MCU) are built into an off-the-shelf package called the ELRS Micro Receiver from BetaFPV. In order to reduce size and weight of the fixed-wing aircraft, we want to integrate the buck converter/LDO regulator onto a single board with the MCU and RF IC. We also want 1 more PWM output (versus the Micro Receiver’s 5) for an additional point of control for the fixed-wing plane. We also want to allow for the possibility of connecting 2 motors, so the battery input will be directly split to 2 output XT60s.
This buck converter will also be missing the reverse polarity protection from the Meghan’s board, as it was deemed not required for this project.
