Arduino shines at fast firmware loops—and frustrates when every sensor, switch, and power lead is temporary. JIGMOD gives Arduino UNO, DUE, and MEGA builders a modular electronic circuit building system: a platform to mount on, an Arduino UNO/DUE/MEGA JIGMOD Adapter to hold the board, and modules that screw down with the included standoffs and screws so the next revision is a rearrange, not a rewire.
That matches why JIGMOD exists: help you succeed at electronic product development. Keep the microcontroller fixed; move the human interface, power, and prototype area as the sketch evolves.
Why Arduino users reach for a modular bench
- UNO/DUE/MEGA stay on-adapter while shields-and-wires chaos moves into labeled modules
- Proto space and controls live on the same platform as the MCU
- Battery and switch modules make portable demos less fragile
- You can harden a layout toward a product without throwing away the mechanical base every sprint
Five JIGMOD modules that pair especially well with Arduino
These five are distinct from the Raspberry Pi article’s set—so together the two posts cover ten different modules from the catalog.
1. Proto Board JIGMOD
Arduino sketches often need a small island of discrete parts before they deserve a PCB. A proto board module on the platform keeps that island mounted next to the MCU instead of floating on a separate breadboard that walks across the desk.
2. Tactile Buttons JIGMOD
Mode selects, start/stop, and debug triggers belong on real buttons. Mounted tactile buttons give the sketch clean digital inputs and give operators something that does not look like a jumper short.
3. Potentiometer JIGMOD
AnalogWrite thresholds, servo positions, and filter knobs are natural Arduino work. A potentiometer module turns those into durable HMI on the platform—ideal for tuning loops while Serial Monitor is open.
4. Servo Interface JIGMOD
Robotics and mechatronics sketches lean on servos. A dedicated servo interface module keeps the mechanical and electrical hookup on the same base as the Arduino, so motion demos survive transport better than three flying DuPont leads.
5. 9V Battery Holder JIGMOD
Classroom kits and field demos still love a 9V. A mounted holder makes battery power part of the fixture—pair it with your sketch’s regulator strategy and you spend less time chasing a clip that fell off mid-demo.
A simple Arduino + JIGMOD starting pattern
- Mount the Arduino UNO/DUE/MEGA adapter on an M, L, or XL platform
- Add Proto Board, Tactile Buttons, Potentiometer, Servo Interface, and 9V Battery Holder as your first five modules
- Wire to the MCU headers as usual—then rearrange modules when the sketch’s I/O map changes
- When the design stabilizes, you already have a coherent mechanical starting point for the next enclosure pass
