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.

Electrical Information

 

Micro USB 5V, 2.54mm pins 3.3V~5V power supply; 1.27mm stamp hole power supply.

1GHz linux IDLE run 90~100mA; cpu-burn run ~180mA

Storage Temperature -40~125

Operating Temperature -20~70

Micro USB 5V, 2.54mm pins 3.3V~5V power supply; 1.27mm stamp hole power supply.

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.
