Original: Pinch: A Fingertip-Sized 32-Bit Arduino-Compatible Dev Board

Short summary

Moddo's Pinch is a fingertip-sized 32-bit Arduino-compatible dev board built around a Microchip SAMD11 (Cortex-M0+ at 48 MHz) with native USB flashing and 15 GPIO pins. With only 4 KB SRAM and ~12 KB usable flash after bootloader, it targets ultra-compact builds like wearables and sensor nodes. The $16 board is available for pre-order with shipping expected in September, and design files are already public.
