Simple breadboard friendly development board designed for C8051F350, microcontroller with built-in 24bit adc.
Usual microcontrollers hobbyists use have ADC with resolution between 8bits (255 steps) and 12bits (4096 steps). When I saw that C8051F350 had 24bit ADC, I was intrigued. Even if we discard few least significant bits, it still has much higher resolution than most microcontrollers.
Before designing PCBs and developing projects with this interesting microcontroller, I wanted to test things out on a breadboard. As I didn't find any breadboard friendly dev boards of my liking, I had to design one myself.

Hellurei! 15 years ago I designed an intercom system for airplanes based on C8051F100. I liked the built-in HW debugging of the chip.
The planes seem to fly still...
That's cool! Nice to hear stories from people using these less-popular microcontrollers. Personally I don't care what core microcontroller has... If it has some specs or features not found in other microcontrollers, then it's a candidate for a project.
@@Hackvlog The feature that stands out in the C8051Fxxx is that the UART baudrate can be up to half the clock frequency, i.e. 50 Mbd at f=100 MHz. Normally baudrates are max f/16. I ran audio samples at 25 Mbd through fiber optic cables.
My design might have design mistakes I only noticed while testing these boards. Because there is a high chance pinout may change, I will figure those things out, before finalizing the design and sharing the files.
Nice to see that someone is using Silabs 8-bitters. They have been my go-to microcontrollers for years now. I use them always if there is no specific reason to use something else.
With these older devices, like 300-series, I prefer the old Silabs IDE over the Simplicity Studio, it is so lightweight.
I've yet to start actually programming these, but I had Simplicity Studio installed... Now I installed older SiLabs IDE and I like it. Starts so fast and doesn't have unnecessary bells and whistles. Thanks!
