tBeacon DIY

 

It is permitted to assemble a tBeacon for your own personal use.

Manufacturing for commercial purposes, for sale, any other profit-making is PROHIBITED.

If you find the beacon useful, please donate to support future development.

 

You can order PCBs via links on dirtypcbs.com.

You'll have to flash the bootloader to the microcontroller before usage. This can be done either with a socket tool or on a prototyping board.
