The M5stack Cardputer Adv is a pocket computer that fits into pockets and comes complete with a keyboard and a tiny display. It is designed to handle rapid prototyping, industrial control, and home control. The system is built around a module called an M5Stack Stamp-S3A core, a low-power, dual-core, Wi-Fi and Bluetooth 5.0 low-energy capable system-on-a-chip. The Cardputer also includes a 1,750mAh Li-ion battery, a high SNR (signal-to-noise ratio) MEMS (Micro-Electro-Mechanical Systems) microphone, and a 3.5mm jack for audio. The base contains magnets so the Cardputer can be stuck to a ferrous surface and holes for LEGO integration. The cardputer can also be used to access the six-axis motion sensor ad IR emitter and record audio, GPS receiver, LoRaChat long-range radio, and more. However, the learning curve begins with a steep learning curve.
