Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ANT | passive | 50Ω single-ended RF port for 2.4GHz antenna connection through integrated balun |
| 2 | VDDR | power_in | Internal 1.28V regulated supply for radio frequency and CPU subsystems; requires 10µF bypass capacitor on all instances |
| 3 | DIO8 | bidirectional | General-purpose I/O with mux options: SPI0SCLK, UART0RTS, timer compare/PWM, I2C0SDA, or digital test bus |
| 4 | DIO11 | bidirectional | General-purpose I/O with mux options: SPI0CSN, timer PWM, I2C0SDA, LRFD output, or digital test bus; supports pull-up/down |
| 5 | DIO12 | bidirectional | High-drive (max 10mA) general-purpose I/O for GPIO12; supports SPI0POCI/PICO, UART0RXD, I2C0SDA, timer, or DTB functions |
| 6 | DIO13 | bidirectional | General-purpose I/O with mux options: SPI0POCI/PICO, UART0TXD, timer compare/PWM, or digital test bus output |
| 7 | DIO16_SWDIO | bidirectional | High-drive GPIO16 and serial wire debug data I/O (mux=5); supports SPI0PICO, UART0RXD, I2C0SDA, and timer functions |
| 8 | DIO17_SWDCK | bidirectional | High-drive GPIO17 and serial wire debug clock (mux=5); supports SPI0SCLK, UART0TXD, I2C0SCL, timer, and DTB functions |
| 9 | DIO20_A11 | bidirectional | General-purpose I/O and ADC channel 11 input; supports low-power comparator positive input, UART, SPI, timer, and DTB functions |
