The Muxcard is a 1mm-thick, credit-card-sized computer that houses an ESP32-C3 microcontroller, a 1.54-inch flexible E Ink display, NFC, Wi‑Fi, Bluetooth, an IMU, and a tiny Li‑Po battery. Its bend-tolerant design and on-card integration push the boundaries of ultra-portable computing while highlighting durability and power challenges in flexible electronics.
The article warns about the potential pitfalls of purchasing ESP32-C3 Super Mini boards, highlighting that some variants lack built-in Flash memory, which can be problematic for users. It emphasizes the importance of verifying the specific chip version, as the Flash-less variant requires external memory and is less common, and advises caution when buying from online sellers due to difficulty in identifying the exact model from listings.
A RISC-V emulator has been used to run a Linux-based operating system on an ESP32-C3 microcontroller, which lacks a memory management unit. The emulator is necessary to access the PSRAM storage as program memory. Despite the limited architecture, the boot-up time is under two minutes, making it surprisingly fast.
