About the Jampad PCB
Jampad is an open source PCB design by Menta013, published on GitHub. It is a 2-layer board measuring 76.2 × 99.5 mm, with 22 components from 6 distinct parts.
Other key parts include the MOUDLE-SEEEDUINO-XIAO and ER_OLEDM0.91_1x-I2C. By type, the board carries 10 switches, 10 diodes and 2 ICs.
It belongs with the keyboards and displays & leds designs in this gallery.
From the project
3x3 XIAO RP2040 macropad with OLED and rotary encoder
Jampad is a compact 3×3 mechanical macropad built around a through-hole Seeed Studio XIAO RP2040. It includes an EC11 rotary encoder, a 0.91-inch 128×32 OLED, and a single SK6812 MINI-E status LED in a two-piece 3D-printed enclosure.
- Counter-clockwise: volume down - Clockwise: volume up - Press: unavailable because the encoder's S1 and S2 switch contacts are not connected in this PCB revision
