Low-cost evaluation board for LPC86x microcontrollers

May 5, 2023 — by Giorgio Mendoza 306 views

The LPC860-MAX by NXP is an evaluation board targeting applications such as motor control, wearables and other consumer products. The eval board is equipped with a 32-bit ultra-low power Arm Cortex-M0+ and up to 54x GPIOs.

This specific evaluation board integrates the LPC86x family of microcontrollers. Refer to the table below to see other MCUs specs from the LPC800 Series. 


  • LPC86x — 32-bit Arm Cortex-M0+ (up to 60MHz) with single-cycle multiplier and fast single-cycle I/O port; 64kB Flash, 8kB RAM
