Ultra-compact 33mm x 10mm board for DIY prototyping.
- STM32F030F4P6 or GD32F130F4P6 MCU
- SOT23 or SOT223 LDO
- VDDA out
If you dont need ADC:
- skip placement CM8, CM7, FB
- short both FB pads
- PA14 SWCLK
- PA13 SWDIO
- PA4 LED
A breadboard-compatible dual non-inverter audio amp built around an opamp.
Exposes most of its internals on pins for more versatility (variable gain, simple filter, ...). Some parts are optional.
Can be stacked to create a mixer with 1 board per stereo channel and 1 board for a master volume.
PCB Breadboard made to fit the pinout of the AdaFruit Feather Line (and other tiny boards and chipouts with a .9"/900mil DIP stance) without compromising on the number of open bus strip holes. also, adds additional bus strips down the middle of the board.
Small development board for using an ATtiny44A or similar 14-pin ATtiny in SMD package on a breadboard.
Minimal hardware design featuring only MCU, breadboard friendly headers with extra power lines, ISP header for serial programming and reset button.
Uses bare chip and limited extra components.
Also usable for ATtiny84, ATtiny441 and ATtiny841.
This is a breakout board for attaching ZIF-50 connector with a breadboard.
I use it to connect EastRising displays to a breadboard, using [this](https://www.buydisplay.com/default/50-pin-0-5mm-pitch-top-contact-zif-connector-fpc-connector) or [this](https://www.buydisplay.com/default/50-pin-0-5mm-pitch-bottom-contact-zif-connector-fpc-connector) connector.
Reflowing these connectors successfuly...
A selection of breadboard jumpers with fixed length. Useful for single layer PCB wich needs this type of jumpers.
The jumpers can be purchased in Aliexpress, or any big chinese store.
The lengths are: 2,5,7,10,12,15,17,20,22,25, and 50 mm
