The SPI connected SD reader gives an extra functionality for this board.
The header is without the NRST pin. The board initialization seems to work even without that signal.
The size (0.23in x 1.55in x 1.95in) is possible when the I/O pins are in two rows on three sides. The board weight is 8g - without the soldered pins.
The red power LED is quite bright. The blue user LED is connected to PB9. There are small switches for boot signals
- S1, Boot1 connected to PB2
- S2, Boot0 connected to dedicated Boot0 pin
This is a very clean board. Only the SWD header is manually soldered and slightly reducing the impression of high quality.
There is no JTAG connector. Instead the SWD signals are in a dedicated header, although without the reset signal.
Without an option for breadboard installation and mounting holes, special design is required for the mechanical mounting of this board in a target system.
