The DevPocket is a new compact, battery-powered debugging and prototyping device designed for mobile hardware hacking. It connects to smartphones via USB-C and allows users to code and run scripts without a PC. Built around the ESP32-WROOM-32UE microcontroller, it supports both Wi-Fi and Bluetooth connectivity. The device features a modular design with a full-size mPCIe slot for custom hardware add-ons, enhancing its versatility. One of the first modules developed is an environmental sensing board that monitors air quality, including metrics like eCO₂ and TVOC levels. The device is open source, inviting developers to experiment and customize it further. Early testing has confirmed successful operation of the onboard sensors. The DevPocket aims to simplify hardware debugging in the field, making it accessible for developers on the go.
