The LilyGO T-Display RP2040 is a Development board based on Raspberry Pi RP2040 which comes with a 1.14 inch color screen with a resolution of 240 × 135 , and costs around $ 10 on Aliexpress .
As Notes Tom 's Hardware , the T-Display RP2040 board isn't the only Raspberry Pi RP2040 board that comes with a screen, but it is much cheaper than alternatives, such as Arducam Pico4ML , which costs around $ 50.
In addition to the display, which is based on the ST7789V SPI display controller, the LilyGO T-Display comes with all the usual features from $ 4 Pico like the Cortex M0 + dual-core processor which can be made to run at up to 133Hz , along with a generous 4MB of flash storage.
The board is programmable via MicroPython and C like any other Pico, and it is assumed that Arduino support might be available in a near future, as it is available on the manufacturer's similar ESP32 board with the same screen.

Although the map has a good complement of expansion options including 15 pin + 12 pin expansion headers with 14 GPIO, Hardware Tom 's points out that it appears to have a different pin layout than the traditional Raspberry Pi Pico. In addition to the fact that it seems wider, it will take time for the accessoires Pico work with the LilyGO T-Display.
However, the card supports two power modes. There's the standard 5V USB-C, which is said to be becoming the standard connector on manufacturers' boards. This is completed with a 1.25mm pitch two-pin JST connector that can also power the board and display via LiPo battery.
The $ 10 package includes the T- board Display RP2040 itself, as well as a connection cable to connect a battery and an expansion header. However, the board was out of stock when we checked at the time of writing.
