Meet the M5Stack Cardputer Adv: a credit-card-sized computer bridging the gap between Raspberry Pi and Flipper Zero. Packed with Wi-Fi, Bluetooth, a built-in keyboard, and color display, it’s built for portability and hands-on tinkering. Strong build quality, active community, and low cost make it a standout for hobbyists and developers. #m5stack #portableco
M5NanoC6 has just joined my M5Stack family. Small but powerful!
M5Stack Cardputer goes off-grid with new Mesh Kit featuring LoRa, GNSS, and Meshtastic support

M5Stack has just launched the Cardputer Mesh Kit, a portable, card-sized Meshtastic communication terminal built around the ESP32-S3-powered Cardputer-Adv controller and a new LoRa expansion module (CapLoRa-1262). The kit is essentially a modular upgrade to the original Cardputer, where the base unit handles the UI via a 56-key keyboard and a 1.14-inch LCD. The added "Cap" module adds a Semtech SX1262 transceiver and an AT6668 GNSS module, allowing for off-grid text messaging and GPS location tracking without relying on cellular networks. Cardputer Mesh Kit specifications: Core Controller (Cardputer-Adv): Wireless MCU module – M5Stack M5Stamp S3A with SoC – Espressif Systems ESP32-S3FN8 CPU Dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz RISC-V ULP co-processor Memory – 512KB SRAM Storage – 8MB flash Wireless – 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 BLE + Mesh 2.4GHz 3D antenna USB – 1x USB Type-C port Expansion connectors for I/Os such as SPI, I2C,
I've added easily customizable color theme support to Cucumber. Simply edit the settings.ini file on the SD card and define your color theme!
This LCD doesn't capture well on camera, but here's the Solarized "dark" theme ported over.
