Description:Cardputer-Adv is a programmable card-sized computer powered by the Stamp-S3A core module (based on ESP32-S3FN8). It integrates a 1.14' LCD display and a 56-key minimalist keyboard for convenient interaction and input operations.In terms of audio, it features an ES8311 audio codec, a high SNR MEMS microphone, an NS4150B amplifier, and a 1W speaker, providing high-quality audio input and output capabilities. Additionally, it has a 3.5mm audio output jack for connecting external headphones or speakers.Internally, it is equipped with a 1750mAh high-capacity lithium battery, combined with a low-power design and an independent power switch to ensure good battery life. It integrates a 6-axis motion sensor BMI270, an infrared emitter, a microSD card slot, and also provides an HY2.0-4P Grove port and an EXT 2.54-14P expansion bus for connecting sensors and other peripherals.The base contains magnets for metal attachment and is compatible with LEG0 hole extensions. This product is suitable for quick function prototyping, industrial control, home automation, and other scenarios.Features:Stamp-S3A core controller56-key keyboard1.14' LCD display160gf comfortable keypress feelES8311 audio codecHigh SNR MEMS microphoneNS4150B amplifier + 1W speaker3.5mm audio output interfaceInfrared emitter6-axis motion sensor BMI270HY2.0-4P Grove portEXT 2.54-14P expansion busmicroSD card slotBuilt-in 1750mAh Li-ion batteryMagnetic back designLEG0 hole compatibleDevelopment PlatformArduinoIDE
