Hello,
I finished up my first Mote last night and will be powering it using a 1s lipo. My external circuit is on a proto board and that just makes me nervous as I don't want to ironically burn the house down while creating gadgets to let me know if I am burning the house down...
I believe something like what is pictured below would do the trick but I can't seem to fine them anywhere, only the larger inline fuses.
Any suggestions?

How about these:

Or these:

Ah, perfect. I was having a difficult time finding them, thanks!
Any suggestions on what amperage fuse to get? My project is all fairly low power: Moteino with RFM69HW, cheap PIR sensor, and a TSL2561 breakout (.6mA max).
Looks like the PICO fuses come in: 0.062, 0.125, 0.2, 0.25, 0.375, 0.5, 0.75, 1, 2A
Thanks.
A 0.25 Amp fuse should be fine. This will enable you to transmit continuously. With a 150ma transmitter and have no issues.
The 0.25Amps at 3.3 V would require some sensitive Kindling to start a flame.
You could look at polyfuse (self resetting) fuses for this.
Mark.
