The tile provides a user-configurable combination of: SW debug & bootloading; 1MB flash & 128KB SRAM; wireless communications (BLE 5.4, Thread, Matter, Zigbee, proprietary); two FM+ (1MHz) I2C ports; two SPI ports; one USART; five 12-bit 2.5Msps ADC inputs (16-bit with oversampling); many timers; ten capacitive touch inputs; one serial-audio interface; IR output; and an on-board LED", "application_notes": [ { "sort": 0, "details": "The single-wire debug port is available on pads 13 (SWCLK) and 14 (SWDIO).
