About the Daughterboard PCB
Daughterboard is an open source PCB design by BoomBoxRobotics, published on GitHub under the CC0-1.0 license. It is a 4-layer board measuring 155 × 80.6 mm, with 118 components from 59 distinct parts.
Other key parts include the BQ25887RGER 2S charger, BQ28Z610DRZR-R1, AP63200WU-7 5V Buck, AP63200WU-7 3V3 Buck and ADS1115IDGSR 0x48. By type, the board carries 50 resistors, 33 capacitors, 9 connectors, 7 ICs, 7 diodes and 4 fuses.
It belongs with the power & battery and dev boards & breakouts designs in this gallery, and the repository also holds 1 earlier revision of it.
From the project
Anubis is a project to create the ultimate open source RC controller utilizing inexpensive consumer parts and clever programming.
A compact open-hardware support board for a DIY ESP32-S3 RC transmitter.
Anubis is an open hardware and open firmware RC controller project built around accessible DIY parts, modern radio-control features, and a design that builders can understand, repair, modify, and improve.
This repository contains the custom daughterboard for the Anubis controller. It sits under a Hosyond 2.8 inch ESP32-S3 display board and turns the early wiring-heavy prototype into a cleaner, more repeatable hardware platform.
