Documentation missing

[eabase]

Hi,

I am missing all the documentation of the various ports, connectors and buttons.

1. Can you please upload the schematics and clearly document the side ports and 2 buttons?

2. How I can connect a GPS?

Also, you are referring to the L67` GPS module which is nowhere to be found.

3. How/where can I get one, and how to connect in the meantime?

@eabase
Hello, thank you very much for your feedback.

1. You can access the schematic diagram of this project Echo-Lite_V1.0, or directly visit the pin configuration interface pinoverview to obtain the corresponding IO numbers for MUC connections with other hardware devices.

2. The connection method for GPS is designed according to the shell structure. You can confirm the GPS connection by referring to the reserved position for the GPS module in this diagram.
   

3. You can purchase this GPS module t-echo-lite from our official store.

Hi @Llgok,

The "pin overview" in the README is impossible to understand!

For example (to mention just a few):

• Why do you have LED_1 pin connected to 3 different pins on the BT chip? Makes zero sense!
• What is the function(s) of the "Two SH1.0 external sockets pin"s?
• What is a "Screen pin"?

@eabase
Hello, I sincerely apologize for the inaccuracies in the README documentation that require corrections:

1.The three LEDs correspond to three distinct onboard LED pins (LED1, LED2, LED3). My earlier description was incorrect—two of these LED pins are already utilized by the bootloader.
2.The 'SH1.0 external socket pins' refer to the two port pins on the board, as shown in the diagram below.

3.The 'Screen pin' is the SPI pin for the e-ink display.

@eabase
You can obtain the pin definitions directly from the code, which is relatively more accurate.pin_config.h

2.The 'SH1.0 external socket pins' refer to the two port pins on the board, as shown in the diagram below.

Well, what are those ports used for? What are they doing ?

[eabase]

Any update?

[Llgok]

@eabase These are external expansion pins used to expand other devices.

@Llgok

These are external expansion pins used to expand other devices.

Sorry, but that statement doesn't say anything at all, and is not helpful.

Can you please add a 2 pictures with all the pins and headers clearly labelled on both the backside and the 2 side connectors next to the USB port?

@eabase Hello, here is the pinout diagram for the SH1.0 connector you requested.

[eabase]

# "CNC-2"
1.  GND
2.  VDD3V3 # +3.3 Volt
3.  P1-04
4.  P1-02

# "CNC-1"
1.  GND
2.  VDD3V3 # +3.3 Volt
3.  P0-23
4.  P0-25

But I can't tell which connector is which from the picture above...

Also, the Px connections seem to refer to General I/O on the nRF52840.

Your schematics and labeling is the worst I have ever seen. I have 6 year old kids who make far better ones. It's a miracle if you can get this device to work based on this. :(

To be a good guy, I tried to figure out where the heck all those connector go and their orientation.
So I also added CNC-3/4 myself. Here you go:
