Canada-based Moddo has designed the Pinch board, which it claims is the world’s smallest 32-bit Arduino-compatible board so far, measuring just 10.9 x 10.5 mm. The board is powered by a Microchip SAMD11 Cortex-M0+ microcontroller with 4 KB SRAM and 16KB flash, features an RGB LED, reset/bootloader button, 3.3 V LDO, a USB-C port, and a total of 15 GPIOs. Moddo Pinch specifications: Microcontroller – Microchip SAM D11 (ATSAMD11D14A) MCU core – Arm Cortex-M0+ processor running at up to 48 MHz RAM – 4 KB SRAM Storage – 16 KB Flash (12 KB for sketches, 4 KB bootloader) USB – 1x USB Type-C port for power, programming (CDC serial), and HID Expansion – 16-pin header (1.27mm pitch) 12x GPIO (D0–D11) 5x analog input (A0–A4) 11x PWM 1x DAC 1x I2C, 1x SPI, 2x UART(multiplexed with USB & D5/D6) Debug – SWD on D5 (SWCLK) and D6 (SWDIO) Misc RGB LED (connected […]
