A UART adapter finally for professionals
μArt launched on August 8, 2018 with 3 votes.
What it does
The μArt is a USB-UART(TTL) adapter that is finally both universal and reliable. It supports all voltages in the range of 1.8 - 5.4 V, it has handshaking and other pins for flashing MCUs, it is galvanically isolated, has various protection circuits, a case, even GPIOs and more. Replace your UART adapter collection with a single quality piece.

I needed to stuff twice the telemetry through the same 115 kbaud line on a Cortex-M0+ that only had 8 kB flash left. Micro-RLE is the smallest drop-in I could come up with: 264 B of Thumb code, 36 B of state, no malloc, worst-case 14 cycles/byte and still lossless for every 8-bit pattern. On the usual sensor streams (ADC, IMU, GPS) it’s 33-70 % smaller than raw output and boots in < 600 µs, so you can fire-and-forget from main() before the PLL even locks. Repo is a single .c file and a 3-function API—replace the weak emit() hook with your UART / DMA / ring-buffer and you’re…
