Module Tester PCB and pre-flashed chip set.
Price: £23.99 (No VAT added at checkout, the price you see is the price you pay)
Now in stock, everything you need to design and test your DIY Eurorack synth module circuits.
If you like building your own Eurorack synth modules but prefer to test them before subjecting your rig to possible shorts and firey carnage, this project is for you.
Rebranded at Olivier's request (as The Noodle Toaster), the Eurorack Synth Module Tester is a compact, portable, blend of bench power supply, MIDI to CV converter, frequency counter, and function generator, tailored to the needs of DIY synth fans, module designers and contract manufacturers.
If you have modules made by a contract manufacturer, you can supply them with one of these for testing purposes, there is scope to modify the code to run specific test programs due to it's open source nature.
If you sell Eurorack modules, you'll like using this to test returns.
Mutable Instruments discontinued the Module tester pcb 2 years ago, we like it so much we have started producing it ourselves from the open source project files.
We improve on the spec of the official MI PCB with this beautiful quality gold plated board made in Germany, unlike cheap PCB's that manufacturers claim to do a 100% E-test on, but which often aren't done properly, allowing board defects that can make troubleshooting DIY kits a nightmare, our PCB is fully electrically tested.
These PCB's are produced in accordance with the highest environmental protection standards, and are the best synth DIY PCB's available
Audio output, square, saw, sine, ramp, triangle waves.
Functions as a basic standalone DIY synth, play notes by plugging in a midi keyboard (outputs notes as 1v per octave CV from the CV output, making this a midi-cv converter too).
Use the gate input to trigger notes from the audio out instead of a continuous tone.
All the above waveforms available simultaneously as an LFO (LFO waveform individually selectable), at a selectable 5,10 or -5 to 5 volts.
Audio input allows VCO's to be calibrated, the code includes a frequency counter for doing this.

Building the DIY Eurorack Synth Module tester
This pcb is a fairly easy build, it uses through hole parts and suits anyone who can solder them. I generally recommend soldering some resistors to a piece of stripboard as practice for an absolute beginner, followed by a very simple project like the Breadboard Friends PCB's. you could build this one after you've learnt to solder like that.
It's important to put the resistor network on the right way round - the polarity is marked with a dot. I'd also recommend taking care soldering the header for the LCD screen on, if you put it the wrong way round your screen will be suspended 3mm off the pcb - much better to put it on so it lies flat against the board.
If you plan on putting this in a case, it's also important to bend the legs of the large electrolytic caps so they lie flat against the board, if soldered upright this PCB will not fit inside. Overall this PCB is ideal for a fairly new project constructor, and incredibly useful for the more experienced!
Here's a Mouser Cart BOM for easy ordering of most parts and for costing your builds. Try ordering several projects at once for lowest prices.
If you're not completely satisfied, You can return these PCB's for any reason within 14 days of purchase for a full refund!
