About the MarcinhoPad PCB

MarcinhoPad is an open source PCB design by Developer-Vini, published on GitHub under the MIT license. It is a 2-layer board measuring 82 × 63 mm, with 16 components from 6 distinct parts.

Other key parts include the MOUDLE-SEEEDUINO-XIAO and ER_OLEDM0.91_1X-I2C. By type, the board carries 7 switches, 6 diodes, 2 ICs and 1 resistor.

It belongs with the keyboards and displays & leds designs in this gallery.

From the project

MarcinhoPad is a simple, custom-built macro keyboard designed using KiCad. Built with mechanical switches and integrated, it serves as a compact shortcut pad to streamline your daily workflow and macro controls.

Custom macropad designed for the Hack Club Hackpad program.

MarcinhoPad is a compact macro keyboard built around a Seeed XIAO RP2040. It features 6 mechanical switches, a rotary encoder for volume control, and an OLED display for visual feedback.

- MCU: Seeed XIAO RP2040 (through-hole) - PCB: 2-layer, under 100mm x 100mm - Case: 3D-printed only, fits within 200x200x100mm - Inputs: 6 switches + 1 encoder (7 total, under 16 limit) - Firmware: KMK (CircuitPython)
