sampled at boot or shared with debug/serial| Pin | Label | What to know | Role |
|---|---|---|---|
| TX | U0TXD (GPIO43) | Used for bootloader output and UART console logs. If repurposed, you will lose the default serial output (and programming via UART0). | Other |
| RX | U0RXD (GPIO44) | Used for bootloader input (download mode via serial). If repurposed, you cannot use the default UART0 download mode for programming the chip. | Other |
| MISO | GPIO45 | Determines flash/PSRAM power voltage (3.3 V vs 1.8 V) at boot. Must match hardware configuration; using as GPIO can upset flash supply setting. | Strapping |
| CS | MTCK (GPIO39) | Default JTAG debugging TCK pin. If JTAG is needed, this pin must be free; it may also be used internally for PSRAM chip select on certain modules, so avoid repurposing it. | Other |
Only if you know the tricks
wired to flash or USB - expect a fight| Pin | Label | What to know | Role |
|---|---|---|---|
| TOUCH_INT | SPICLK_P | Used only on variants with Octal SPI interface (e.g. ESP32-S3R16V) as part of the differential clock pair. On such chips it operates at 1.8 V and is reserved for the high-speed octal SPI clock, not for general GPIO use. | Flash |
| MOSI | FSPICS0 | Used to select the external flash chip. It is required for flash access and cannot be repurposed without losing flash connectivity | Flash |
| SCLK | SPICLK_N | Used only on variants with Octal SPI interface, as the negative leg of the differential clock&. On such chips it operates at 1.8 V; it should be avoided for GPIO to prevent conflicts with the octal flash/PSRAM clock. | Flash |
These are recommendations, not hard rules - with the right pull-ups, timing and boot-state awareness most pins can be made to work. When in doubt, start green.

Across 15 pins (2.54 mm pitch), the LilyGo T5 4.7 Inch E-Paper V2.3 exposes 11 GPIO plus 3V3, 5V, GND and VBAT for power.
For peripherals, I²C is mapped to SDA on GPIO18 and SCL on GPIO17, while TX/RX on GPIO43 and GPIO44 cover serial logging and flashing.
On the analog side there are 5 ADC-capable pins for sensors and battery monitoring and 1 capacitive-touch inputs.
If you want zero surprises, SCL, SDA, IO16 and IO15 are free of any such role - the safest first picks. 4 of the exposed pins carry boot-time or system duties on the ESP32-S3 (TX, RX, MISO and 1 more).
Getting started

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 $39.99 - above the ~$30 typical for ESP32-S3 boards.
Only 11 GPIO are left for your own hardware - the display and onboard peripherals claim the rest.
Onboard you'll find 8MB (OPI) PSRAM, an ePaper 4.7" 540x960 display with touch, a microSD slot, a PCF8563 RTC and Reset/Boot buttons.
The LilyGo T5 4.7 Inch E-Paper V2.3 is the ESP32-S3 revision of LilyGo's 4.7-inch e-paper board - a 960×540 ED047TC1 panel with 16 grayscale levels, built for e-book readers, IoT dashboards and battery-powered signage.
It runs an ESP32-S3-WROOM-1 (WiFi 802.11 b/g/n + Bluetooth 5.0 LE, native USB) with 16MB Flash and 8MB PSRAM, and adds an optional GT911 capacitive touch overlay, an onboard microSD slot and a PCF8563 RTC over the original WROVER model.
Powered and programmed over USB-C, with a JST-PH 2.0 Li-Po connector and deep-sleep support. Note: the GPIO map differs from the original ESP32-WROVER T5 4.7.
