World’s Smallest Arm Microcontroller: HC32L110 – Showcase & Programming Guide

Thank you to PCBWay for sponsoring this video. Check out PCBWay at the following link: The HC32L110B6 microcontroller from HDSC is an absolutely tiny Arm M0 powered microcontroller. It is housed on a simple development board, the LilyGo T-HC32 that comes in at an affordable price of around £7. It features user input in the form of two buttons, a reset button and a user button but does lack some expansion options in terms of GPIO. It also features an RGB LED. The board comes in at 30 x 22mm. The HC32L110B6 chip features an Arm Cortex M0 processor core running at up to 32MHz. It has 32KB of onboard flash memory and 4KB of RAM. There is a 12-bit ADC capable of sampling at an impressive 1MSPS. There are 8 useable ADDC channels. In terms of peripheral interfaces, there are two UARTs (including LPUART), one SPI and I2C controllers. Programming can be done in the Keil MDK development environment, details can be found in the link below.
