FLIR One: USB-C and battery mod.

FLIR ONE is a nice product, with an extremely limiting battery and bad software. (Luckily, third-party software is much better)

You may say the battery has two reasons to be there:
1: Limit useful time: pushing users to a more expensive product.
2: Obsolescence by design: become useless as the battery age and stops working.

1: remove the need for battery and charging.
2: replace the MicroUSB with USB-C

Special tools: You will need one security T5 (Torx5 with a hole in the middle)

The original USB connector extracted from FLIR One
Fast mapping of the connections between USB and mainboard.
1: By heating the MicroUSB up, I removed it from the retainer.
2:USB-C OTG to MicroUSB adapter will be the donor for USB-C
3: This 4-pin motherboard connector will be re-used.

Using a Dremel multi-tool, I expanded the slot it the black connector retainer and the main body.
Using adapter (2): after de-soldering its female MicroUSB – I glued the USB-C connector inside the black retainer using epoxy.

Please note: A reader of this article told me that I got the D+/D- swapped in this post.
If what you do does not work: swap D+/D- (it’s harmless to swap them, but only the correct way will work)

The new connector in place, wires soldered to the motherboard connector.
Mainboard in place, observe the orange wire providing power where needed.
No more battery.

Assemble, and throw away the battery.

USB-C in place.

There is no more need for charging or switching on the device. Also, it does not run out of juice after 5 minutes anymore 🙂
