pinout for waveshare 1.54 inch e-paper on fanstel BT832X

[Jokostyl3]

Hello,

I have started 3 years ago an e-surf project with a friend .
Our first wireless remote build with arduino and nrf42 modules and i2c displays was fonctionnal, but we need better transmission, because our board is in fiberglass and carbon fiber, which attenuate a lot the signal. Later we will need to activate the power amplifier and also start to experiment the rssi data to make a security failsafe. If the rider fall off the board the motor will stop running.

We choose to buy some Fanstel BT832X because there is a power amplifier embeded., but we are confused with the spi interface pinout.

For now we have Fanstel and NRF development board and we don't find on the manuals how to wire our new e-paper display.

We want to try this, but we fear make some magic smoke ;-(
If somebody can help us it would be great.

1.54 Inch e-paper display <--> fanstel BT840(832) development board

VCC -- VDD
GND -- GND
DIN -- SWDIO
CLK -- SWCLK
CS -- P27 / SCL
DC -- P26 / SDA
RST -- P18 / RESET
BUSY -- P100 SWO

We try to make an Hello world with an exemple from the GxEPD2 GitHub :https://github.com/ZinggJM/GxEPD2/blob/master/examples/GxEPD2_GFX_MultiDisplayExample/GxEPD2_GFX_MultiDisplayExample.ino

But unfortunately there is not the BT832X board on this example, any help will be appreciate.

I haven't used these yet, but it looks like @NeverDie has a project using the amplifiers here:

Hi, thanks for the answers.
For now we don't find any elements about the pinout wiring . we are still debugging and we will provide code tomorow if we don't succeed. We will check with a multimeter the GPIO. We appreciate your help. see ya
