Fine - with a little care
2 pins · 2 things to knowTXGPIO43 UART0 transmit pin (U0TXD), default serial console TX UART
Used for bootloader output and UART console logs. If repurposed, you will lose the default serial output (and programming via UART0).
RXGPIO44 UART0 receive pin (U0RXD), default serial console RX UART
Used for bootloader input (download mode via serial). If repurposed, you cannot use the default UART0 download mode for programming the chip.
The LilyGo T-Deck Plus breaks out 4 pins in total: 2 GPIO for your project, with 3V3 and GND handling power.
For peripherals, TX/RX on GPIO43 and GPIO44 cover serial logging and flashing.
2 of the exposed pins carry boot-time or system duties on the ESP32-S3 (TX and RX).

About this board
At its core is the ESP32-S3 - a dual-core Xtensa with vector extensions suited to AI workloads.
Expect to pay about $70.99 - above the ~$29 typical for ESP32-S3 boards.
Only 2 GPIO are left for your own hardware - the display and onboard peripherals claim the rest.
Onboard you'll find 8MB (OPI) PSRAM, an IPS LCD 2.8" 320x240 display with touch, a microSD slot, LoRa (SX1262), GPS (u-blox MIA-M10Q), a microphone (Dual MEMS array), a speaker, an audio codec (ES7210), an amplifier (MAX98357A), battery charging (TP4065B) via JST 1.25 and Reset/Boot buttons.
It flashes over native USB - no serial-converter driver needed, which isn't a given among ESP32-S3 boards.
The LilyGo T-Deck Plus 1 is an advanced ESP32-S3-based development board designed for versatile applications. Featuring integrated WiFi and Bluetooth 5, it offers seamless connectivity for IoT and embedded projects.
The T-Deck Plus 1 includes a 2.8-inch IPS LCD display with touch support, making it ideal for graphical user interfaces. It also comes with 8MB PSRAM and 16MB Flash for enhanced performance.
With multiple GPIOs, ADC, PWM, I2C, SPI, and a built-in keyboard, it is perfect for handheld devices and portable applications.
- BlackBerry-style backlit QWERTY keyboard (managed by an onboard ESP32-C3 over I2C)
- Trackball navigation module with center-press button
- LoRa SX1262 selectable 433 / 868 / 915 MHz, +22 dBm, u.FL antenna
- Onboard u-blox MIA-M10Q GNSS module (Quectel L76K on some units)
- 2000 mAh built-in LiPo battery with TP4065B charger IC
- ES7210 codec with a dual MEMS microphone array and MAX98357A speaker amplifier
