JHEMCU GHF13AIO – first 16x16mm sized AIO board
JHEMCU will be releasing GHF13AIO, the first AIO 16x16mm mount size flight controller and ESC on single board. The main CPU is F411, with popular Betaflight target MATEKF411. On board ESC is rated for 13A @ 2-4S battery input. The GHF13AIO has 2 UARTS, Current sensor, output pads for WS2812 LEDs, buzzer and SCL/SDA pads (for compass sensor as an example). The FC has also motor wires and 4 additional LEDs at the corners of the board.
Weight of the board is only 4.3g. This makes it the lightest 13A AIO flight controller in the market.

That’s insane! Counting the weeks to the first 6S F7 + BLHeli32 16×16 AIO now 😄
Oh man the could have included a VTX 😂
I fear it will be noisy… Anyway looking forward to trying it!
Need 3 uart port for GPS, receiver and dji osd.
is there any available pad for sosftserial uart port?
There is seen tiny small pad under the MCU
are those M5 and M6?
No, those tiny pads are MCU programming pads (the MCU is preprogrammed in the factory using them). If you need F4 and 16×16 format, and you need 3 uarts, then I suggest to look at the Flywoo Goku 16mm stack https://flywoo.net/collections/goku-stack/products/goku-f4-20a-stack-v2-1-mpu-6000-16mm-x-16mm-fc-esc. It has 2 pads (B06, B07) that can be used as software serial.
Why the spec is so ambigious?
There are onboard 4 ESCes, is the 13A figure for each ESC or for 4 of them?
If 13A is for each of them, there could be a combination of peak 40A (conservative figure)
aren’t the power pads are too small?
Hi, usually the manufacturer specifies the MAX ESC current for each ESC. So this board is 13A per one ESC and the max total power output can be like 52A. But this is only theoretical values. In the reality there can be short bursts of even more current. Unfortunately the only available pictures are low quality and I cannot determine the exact model of the mosFET chip and cannot say anything about the true power output potential.
Power pads are reasonable size. It is more the copper layer thickness that matters more. 13A is not a big deal for the FC. Take a look at the Flywoo GOKU 16x16mm sized 35A(!) ESC (https://flywoo.net/collections/goku-16×16-stack/products/goku-bs-35a-2-6s-esc-16x16mm). It has more than 120A of total current output! Crazy little board.
hey, I cannot find the UART1 TX on this board. How can I use UART1 whilst UART2 is hooked up to my reciever.
TX1 output for UART1 is actually marked as RX pad next to the VIDEO pad.
Hello, According to the wiring diagram, there is a RSSI pad near the USB connector. However, CLI dump shows “resource ADC_RSSI 1 NONE”. Do you know which pin the “RSSI” pad is connected?
According to the JHEMCU GHF13AIO specs, the board target is MATEKF411. And according to the MATEK F411 specs, the RSSI pad is connected to the PA0 pin (Rssi pad: PA0 TIM5_CH1).
Thank you! I am using this board for a 2-inch hexacopter with my original frame (M5 on the LED_STRIP pad and M6 on the SCL pad with a timer and a DAM enabled), so usable pads are very important.
