LILYGO is a engineering team of open source software and hardware. We are making development boards based on IOT chips with additional different functions. Some of our most popular products include the TTGO T-display ESP32 and the LilyGO TTGO T-display Module. Both of these products are based on the Espressif ESP32 chip and feature a built-in TFT color display. The CP2104 USB to serial converter makes it easy to program, even as an Arduino.
RP2040 is Raspberry Pi’s debut 32-bit dual-core microcontroller, designed to bring the foundation’s emphasis on performance, low cost and ease of use to embedded projects. Featuring two ARM Cortex-M0+ cores, significant on-chip RAM and support for C/C++ and MicroPython, it powers low-cost boards such as the Raspberry Pi Pico and smaller variants like XIAO designs. The chip’s USB mass-storage boot, broad IDE compatibility and a port of TensorFlow Lite make it attractive for rapid prototyping, micro machine‑learning, IoT and hobbyist applications. Compared with alternatives like the ESP32, RP2040 trades higher clock speed for architectural simplicity and strong software support; vendor boards and upgraded modules (for example, wireless-enabled RP2040 Connect variants) add sensors, security, and connectivity. Its low unit cost has spurred a wide ecosystem of third‑party modules and development boards, keeping it relevant for education, consumer devices and embedded product development where ease of use and low BOM matter.
Klipper is a 3D printer firmware that combines the power of a general-purpose computer with one or more micro-controllers. It is designed to improve print quality and speed, with more sophisticated motion processing and the ability to drive many more steps per second than other firmware such as Marlin. Klipper can be run on a Raspberry Pi, with a recommended hardware of Raspberry Pi 2, 3, or 4. It can also be used alongside OctoPrint with a plugin installation. Klipper is a free software that is designed to enhance 3D printer performance.
