### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-S3FN16R8 | MCU | https://wiki.lilygo.cc/datasheet/esp32-s3_datasheet_en.pdf |
| Semtech SX1262 | LoRa radio (BUSY GPIO13, RST GPIO17, DIO1 GPIO45) | https://www.semtech.com/products/wireless-rf/lora-connect/sx1262 |

_Notes:_ All files verified live in Xinyuan-LilyGO/T-Deck (master branch) and on wiki.lilygo.cc, matching the batch's known_links. Pin definitions for the ST7789 display/radio are in the repo's examples/UnitTest/utilities.h (referenced in batch known_links) rather than as a standalone document.

### Software & technical files

| | |
|---|---|
| Hardware source | LILYGO publishes board examples, schematics and keyboard firmware. |
| Arduino configuration | ESP32S3 Dev Module; 16 MB flash; OPI PSRAM |
| USB recovery | Hold the trackball’s center button while connecting USB; reset after uploading. |
| Keyboard firmware | Separate ESP32-C3; programming requires an external USB-to-UART adapter and the six-pin header. |
| Microphone caveat | Maker examples reserve the GPIO0 button when the microphone is enabled. |
| Display/library matching | Use the repository’s ST7789 initialization and bundled library versions when debugging display faults. |

### Build connections

| | |
|---|---|
| Grove limitation | GPS occupies the Grove signals; this connector is unavailable for general expansion. |
| Power enable | Drive GPIO10 high for battery-powered operation. |
| Shared SPI | Display, microSD and LoRa share SPI. Keep inactive devices’ chip-select lines high. |
| SPI pins | SCK 40; MOSI 41; MISO 38. Chip selects: display 12, microSD 39, radio 9. |
| Radio control pins | BUSY 13; reset 17; DIO1 45 |
| I²C pins | SDA 18; SCL 8; keyboard interrupt 46 |
| GPS UART | Maker GPS example uses TX 43 / RX 44 and detects L76K or u-blox settings. |
| Audio pins | Speaker WS 5 / BCK 7 / data 6; microphone MCLK 48 / LRCK 21 / SCK 47 / data 14. |
