Wren PIC18F Embedded Module

The Black Oak Engineering (BOE) Wren PIC18F Embedded Module (#BE-WREN) is a compact  computing platform based on the popular Microchip PIC18F47Q84.  It has breakouts to add a variety of daughterboards, including boards with a MikroBus interface.  It includes a rechargeable lithium polymer battery and a rugged ABS enclosure with side flange mounts.  Thus the Wren is ready for many challenging control and data capture applications.   

A Board Support Package (BSP) and a complete set of various tested drivers are available at our GitHub.  BOE releases source code and other collateral under an attached MIT license.
