This page needs to be properly filled according to the New Device Howto and the New Device Page guide.

A comparably small development board (though larger than most other F1Cx00s boards), with two USB Type-C ports.

Identification

The PCB has the following silkscreened on it:

Lctech Pi F1c200s v1.1
    (303F1C200S1)
  www.lctech-inc.com

Older versions are marketed as CherryPi, with a cherry logo silkscreened on the top. Newer revisions (v1.1) have no logo, just the "Lctech Pi F1C200s" name. All share the (now defunct) "www.lctech-inc.com" URL. Nothing is printed naming-wise on the back.

Sunxi support

Current status

Mostly covered by the generic F1C100s support in both Linux and U-Boot, DTs under review.

Images

Optional. Add MANUFACTURER DEVICE specific sunxi ROM images here. E.g. a livesuit image or some other linux image which uses linux-sunxi code. Do not put non-sunxi images here, they should live under See also. If no sunxi based images are available, this section can be removed.

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

Mainline U-Boot

Not yet merged, but initial patches posted.

Mainline Linux Kernel

Not yet merged, but initial patches posted. Use the suniv-f1c200s-lctech-pi.dtb device-tree binary.

Expansion ports

The board features two single-line rows of header pins, which are not populated. The shorter header on the right hand side has the first 12 pins from PortE, but no Vcc or GND pin:

digital header
1 PE0 UART0-RX I2C2-SCK
2 PE1 UART0-TX I2C2-SDA
3 PE2 GPIO-130 CLK-OUT
4 PE3 GPIO-131 RSB-SCK
5 PE4 GPIO-132 RSB-SDA
6 PE5 GPIO-133
7 PE6 GPIO-134 PWM1
8 PE7 SPI1-CS UART2-TX
9 PE8 SPI1-MOSI UART2-RX
10 PE9 SPI1-CLK UART2-RTS
11 PE10 SPI1-MISO UART2-CTS
12 PE11 IR-RX CLK-OUT

The longer header on the other side provides both 5V and 3.3V (plus the only GND pin), a few digital signals, but also many analogue ones:

analogue header
1 5V
2 PD12 I2C0-SCK
3 PD0 I2C0-SDA
4 GND
5 RST
6 3.3V
7 PA3 SPI1-MISO UART1-TX, GPIO-3
8 PA2 SPI1-CLK UART1-RX, GPIO-2
9 PA1 SPI1-MOSI UART1-CTS, GPIO-1
10 PA0 SPI1-CS UART1-RTX, GPIO-0
11 A-GND
12 TV-OUT
13 LRADC key resistor network
14 FMINL (Line-In)
15 FMINR (Line-In)
16 OUT- (from amplifier)
17 OUT+ (from amplifier)
18 HPCOM (Headphone)

Tips, Tricks, Caveats

FEL mode

The BOOT button connects the SPI0_MISO pin to GND, thus preventing SPI-NAND boot. If no SD card is inserted, this triggers FEL mode.

Serial port

The device features a CH340 compatible USB to serial adapter chip, which connects the SoC's PortA UART1 pins (PA2, PA3) to an USB Type-C connector. So serial console just requires a USB cable.

Also known as

Initially this device seemed to have been sold under the Cherry Pi brand name, from the same manufacturer. Newer versions and the current website just use the "Lctech Pi" name now.
