Tamagotchi Uni Circuit Board Power Off Switch

The Tamagotchi community is filled with some of the most creative people! You already saw that Orange_night on Reddit modified their Tamagotchi Uni to feature a power off switch, well now another member of the community has also created a solution.

Marcelmono on Reddit has just announced that they have created a little circuit board that will allow your Tamagotchi Uni to fully power off! Marcelmono was Abel to research the Tamagotchi Uni schematics and looked up the power-regulating chips specification to figure it all out. The modification will require some soldering to install what they’re calling the “Patchi-OFF!” board. 

How does it work exactly? Well here’s the technical jargon provided from Marcelmono:

Test points are accessible pads outside of a circuit in order test the function of said circuit after manufacturing. 

A chip on the Uni that regulates power has a pin/input named “SHDN” (Shutdown). 

The variant of the chip the Uni uses needs a “high” voltage applied to the “SHDN” pin to initiate the shutdown. 

By connecting the 3V3 (3,3 Volt) test point to the SHDN test point, a “high” voltage is applied to the chips “SHDN”-pin/input and it shuts down the Uni. 

The Patchi-OFF! board connects those two test points, but only if the conductive pad on the bottom of the rubber reset button presses down on the contacts on the board and completes the circuit.

Marcelmono is selling both the Patchi-OFF! Tamagotchi Uni Shutdown button circuit board for €7, and a Tamagotchi Uni Patchi-OFF! Shutdown button installation service on your existing Tamagotchi Uni for €25! Both are available on Marcel’s Tama Spa & Repair Ko-Fi page.
