Joranalogue Test 3 DIY Kit

Joranalogue Test 3 DIY Kit is a kit for assembling a specialized tool for measuring voltages and currents in your Eurorack modular system. This single board can replace a cumbersome test setup with multiple multimeters, custom cables, and so on.

Two buttons allow cyclic switching of the display on the LED screen between voltage, current, and peak current measurements across three power rails. Peak current values are continuously updated in the background, ideal for quickly identifying maximum currents.

In addition to measuring the consumption of individual modules, Test 3 also allows testing power supplies and cables, measuring system-wide metrics (up to 1A on each rail), debugging homemade modules, powering prototype boards from the main system, and more.

The Test 3 DIY Kit is designed for straightforward self-assembly, requiring only soldering work and basic tools. It can be assembled either as a standalone board or as a full Eurorack module with the additional purchase of the Front Panel Kit faceplate. Most vendors bundle both kits together. With just 11 soldering components, it's a great introductory DIY project in synthesis!

Key features:
- Measurement up to 20V and 1A per rail, including +5V
- 20mV resolution for voltage, 1mA for current
- Continuous tracking of peak currents
- Pre-soldered SMD components
- Milled aluminum panel with durable graphics (module)
- Reverse polarity protection, hardware included
- High-quality components, assembled in Belgium
