Power Pins<\/a><\/strong>
5V – this is the 5V power from the USB input.
GND – this is the common ground for all power and logic.
3V power output – The new version has a 3.3V power output pin for up to 500mA
GPIO Pins<\/strong>
D4 to D7 – can be used as either digital inputs or outputs.
C0 to C7 – can be used as either digital inputs or outputs.
I2C Pins<\/strong>
SCL – the I2C clock signal is on D0.
SDA – the I2C data is on D1+D2.
I2C switch<\/strong> – The new version has a switch that connects D1 and D2 for easy I2C interfacing. Move the switch to ON to use I2C and\/or the STEMMA QT connector. You can then use either D1 or D2 for SDA.
On the original version only: Note that there are two pins (D1 and D2) which must be tied together and treated as one to use I2C.<\/p>\n\n\n\n

SPI Pins<\/strong>
SCLK – the SPI clock signal is on D0.
MOSI – Microcontroller Out, Serial In is on D1.
MISO – Microcontroller In, Serial Out is on D2.
CS0 – Chip Select is on D3. This is not used by Blinka, instead use one of the GPIO pins from above (see example section).<\/p>\n\n\n\n
