Flidor | Development Interface Board
Agora application development requires the use of the Flidor development interface board. Flidor is a programmer, debugger, and breakout interface for Tectonic Edge™ compatible target devices deisgned by Embedded Planet such as Agora. Flidor provides adjustible power to the target MCU and connects it to a computer via USB for debugging in addition to its breakout capabilities.
