Replacement parts

Hardware options to repair or modify your TRMNL.

Written by Ryan Kulp

We agree with iFixIt - you have the right to repair. Below are a few ways we can help you maintain a functional device, forever.

Quick Links:

TRMNL OG

EPD (screen)

We'll sell you one for $50 (including shipping), or you can get this waveshare one in US Store or this UK Version. Email [email protected] and see our disassembly + assembly guides.

Case enclosure

Have access to a 3D printer? Check out the open source designs here.

Alternatively we'll send you a native case for $10 + shipping. Email [email protected] and see our disassembly + assembly guides.

Battery

TRMNL (OG) maximum space for the battery is 62x31x10mm and uses a JST-GH (1.25mm pin) configuration.

Unfortunately we can't send "loose" batteries, but this one (1000mAh) will fit. Alternatively this option provides 3x the power (3000mAh), but does not fit in the native TRMNL enclosure. If you prefer a longer battery life, consider pairing the larger battery with one of our many 3D printable case designs. Watch this assembly video for installation steps.

Additional EU Battery Options

This 1200mAh option would be fit and work properly: https://ampul.eu/en/battery/5825-li-pol-battery-1200mah-37v-753334

This large capacity version would be a very tight fit, it already has a proper connector, a large capacity, and an integrated protection board https://ampul.eu/en/battery/6148-li-pol-battery-3000mah-37v-103665

Additional US Battery Options

PCB (main board)

We'll send you one for $10 (plus shipping). Email [email protected] and watch this assembly video for installation steps. We will also flash the latest firmware on your behalf, or you can do so in 1 click here.

We'll send you a new one for free, plus a little help for postage. Email [email protected] and follow these steps to replace it.

We can sell you a replacement screen for $70. We currently prefer for the device to be shipped back to us since we don't have re-assembly guides available yet.
