Internet of Things (IoT) specialist LILYGO has launched a new version of its compact T-Display development board — this time packing a Raspberry Pi RP2040 microcontroller underneath a 1.14" color display.
LILYGO showed off the design of the T-Display RP2040, as the new board is named, back in July. Based on its earlier T-Display ESP32 design, the breadboard-friendly microcontroller kit features a USB Type-C connector for data and power, 2.54mm GPIO pins to both edges, and two user-addressable buttons
Its biggest feature, though only relatively speaking: A 1.14" full-color IPS LCD display, offering a 240x135 resolution. Where the original design had an Espressif ESP32 module, this variant — as the name implies — swaps it for a Raspberry Pi RP2040, the same chip at the heart of the Raspberry Pi Pico.
To the microcontroller's on-board dual-core Arm Cortex-M0+ processing cores, eight programmable input/output (PIO) state machines, and 264kB of static RAM (SRAM) LILYGO has added 4MB of external SPI flash and a two-pin JST connector for an optional lithium-polymer battery.
Microcontroller boards with integrated screens are relatively unusual, and ones based on the RP2040 rarer still. The AI-focused Pico4ML from Arducam has one, alongside a camera and microphone; an upcoming design from Oak Development Technologies, the Inky Tree 2040, adds an e-paper panel.
The LILYGO T-Display RP2040 is now available on AliExpress at $9.98 with unsoldered male headers and a JST cable — a 20% saving over the usual retail price.
