Introduction of Lichee Pi
The LicheePi is a delicate, single-board computer, running on the low-cost Allwinner V3S platform which is popularity in recent years. It can be used for beginners to learn Linux or for product development. it offers a wealth of peripherals (LCD, ETH, UART, SPI, I2C, PWM, SDIO…) and powerful performance.

408MHz linux IDLE run 90~54mA; with screen operating current ~250mA Storage Temperature -40~125 Operating Temperature -20~70 |
The temperature when running the Linux stress test is only slightly higher than the body temperature.
Lichee Pi support many OS such as: Linux, RT-Tread, Xboot or no OS.
Like most MCU, the Lichee Pi can connect to several low-speed interfaces, such as GPIO, UART, PWM, ADC, I2C, SPI, and more. Moreover, it can run other high-speed peripherals such as RGB LCD, EPHY, MIPI CSI, OTG USB, and more. The Lichee Pi has an integrated codec that allows direct connection to a headphone or microphone.
Display Connector:
The universal 40P LCD comes with a led back light and four-wire lines, electrical resistance touch, which is very suitable for display and interaction. A13 also supports four-wire resistance touch function, can carry out two-point touch detection.
This interface is compatible with the interface of ORIENT DISPLAY products.
