MODULAR HARDWARE // CARD-EDGE SENSOR & CORE MODULES

PUREmodules — Solderless Low-Power IoT Prototyping Ecosystem

PUREmodules is an open-source hardware ecosystem built on the Pure Engineering Modular Sensor Architecture. Engineers snap wireless CoreModules (nRF52832 BLE, LoRa, Wi-Fi) directly into environmental, optical, and thermal sensor boards using 62-mil card-edge connectors—eliminating breadboards and jumper wires.
