Radix - ECHO

RADIX-ECHO is a compact and versatile PIC development PCB, economized for size and portability. Supplied with a PIC16F or 18F device, the PCB delivers an efficient and effective development experience. The PCB includes USB to UART functionality (Useful for boot loading), a selectable power supply, an ICSP header, and all I/O pins broken out into headers.

NOTE: This variant is currently supplied with the PIC18F56K42

These boards are Proudly South African – Designed assembled and supported by Haventechnik, a local company based in Johannesburg.

Please Note: You will require an external programmer such as a PICkit to program this board.
