PIC18F16Q40
Curiosity Nano
Info:
Peripheral signals shown in the image above, such as UART, I
2
C, SPI, ADC, PWM, and others, are
shown at specific pins to comply with the Curiosity Nano Board standard. These signals can usually be
routed to alternate pins using the Peripheral Pin Select (PPS) feature in the PIC18F16Q40.
5.1.2
Using Pin Headers
The edge connector footprint on PIC18F16Q40 Curiosity Nano has a staggered design where each hole is shifted 8
mil (~0.2 mm) off-center. The hole shift allows the use of regular 100 mil pin headers on the board without soldering.
Once the pin headers are firmly in place, they can be used in normal applications like pin sockets and prototyping
boards without any issues.
