Development board for PIC16F1938


Raj over at Embedded Lab has designed a development board for PIC16F1938:

The PIC16F1938 is a versatile 28-pin MCU belonging to Microchip’s extreme low power microcontroller family featuring nanoWatt XLP technology, 28KB of programming memory, 1KB of RAM, 11 ADC channels, and tons of other peripherals. A while ago, I designed a development board for this MCU and I thought it would be worth sharing this design here. The development board features an onboard USB-UART bridge to support the ds30 Loader for easy programming of the PIC MCU. All I/O pins are accessible through 2×5 headers.

  1. This pic is indeed very impressive, I’ve made a floppy drive controller with it to copy 720KB PC/MSX and 880KB/960KB Amiga floppies to the PC. It even controlled the stepper motor for the drive head directly using a step stick set to 8x microstepping. Some floppies were hard to read and with microstepping managed to get all the data off the disk. Especially those disks that came loose from the central hub, glued it with super glue, but were of course off center. No problem with the micro step controlled stepper motor.
    Together with the PIC16F1827 this is the go to mcu for many of my prototype projects, and even the basis for a more permanent version.
