A Selection of Ergogen v4 Footprints

Tailormade in the fashion of today.

Microcontrollers

• xiao-ble.js - A footprint for the Seeedstudio XIAO nRF52840. Uses smd pads for the standard GPIO pads. For the interior SW pins, Reset pin, Battery pins, and NFC pins, the footprint features through-hole pins. The pins intersect with small edge cut windows so that you can solder them from the underside of a PCB. (Update, Feb. 2026: Now using the KiCAD 8 footprint syntax. Should coexist with Ceoloide's footprint library.)
• xiao-ble-kicad5.js - A footprint for the Seeedstudio XIAO nRF52840. Same as above, but using the older KiCAD 5 footprint format in case you're working with an older build that's not leveraging template: kicad8.

Accessories

• buttonrightangle.js - An MJTP1117 right angle pushbutton.
• gbareversible.js - A reversible Game Boy cartridge slot footprint for all you TypePak fans out there. Based on Martin Refseth's Game Boy KiCad Library.
• spdtrightangle.js - An EG1213 right angle power switch.

Encoders & Friends

• lowproro.js - A footprint for the SIQ-02FVS3 low profile rotrary encoder.
• lowprothumb.js - A footprint for the SLLB510100 low profile rotating thumb switch. (Similar to the rocker switch found on 00s CD and MP3 players.)

Mounting Holes

• mountingholem2.js - An Ergogen version of the MountingHole_2mm_Pad_Via mounting hole. It fits an M2 screw and has one of those metal circles with several smaller circles around the paremeter.
• mountingholem3.js - An Ergogen version of the MountingHole_3mm_Pad_Via mounting hole. It fits an M3 screw and has one of those metal circles with several smaller circles around the paremeter.
