I reviewed your concept: an ESP32 DevKitC plug-on shield carrying shared I²C connectors for GPIO21/SDA and GPIO22/SCL, plus power and ground, intended for the Adafruit fuel gauge, LiPo charger, BME280, Waveshare 0.91″ OLED, and a LiPo battery.
No project changes were made. Before implementation, the exact ESP32 DevKitC revision/header spacing and each module’s connector pin order must be verified; the design also needs a safe battery/USB charging and power-path architecture so the ESP32 and charger cannot back-feed each other. The current project remains unchanged with its existing RP2040 component and single net.
Execution stopped because your ACUs ran out.
