Hi @rahuljeyaraj ,

Welcome to the MakerGram community forum, There are several capable development boards available right now for the application. I'm sharing the one we have at our MakerGram inventory,

For small models, I recommend using - XIAO ESP32-S3 Sense along with Edge Impulse platform to create the model, Here the processing is managed by the esp32 Core itself. It maybe feel slower if the mode it bit heavy.

next option for small models is Seeed Grove Vision v2 camera where all the processing will done in the inbuilt "Arm Cortex-M55 & Ethos-U55" and you can get the inference results via the I2C or UART from the board, later you can process with Arduino or any XIAO board itself.

If the model is moderate in size, better to go with Raspberry Pi and v2 or v3 camera and use the Edge Impulse models.

Currently, we have these board available.

@mahesh02 From the current Arduino ESP32 board files, we don't need to install the ESP-NN separately.

But try to choose the esp32 board version 3.1.3 and check, as I also faced issues with the latest esp32 board file.

Hi @Vishnuraj2003, I see you have A203v2 Carrier Board and it will support M.2 Key M disk 2242 as per the product page.

@Abhay Can you try one more method

Downloaded both boards, “Seeed nRF52 Boards” and “Seeed nRF52 mbed-enabled Boards.”

Copy the adafruit-nrfutil from

/Users/<user>/Library/Arduino15/packages/Seeeduino/hardware/mbed/2.9.2/tools/adafruit-nrfutil/macos/adafruit-nrfutil

to

/Users/<user>/Library/Arduino15/packages/Seeeduino/hardware/nrf52/1.1.8/tools/adafruit-nrfutil/macos/adafruit-nrfutil

Then chmod -x the copied file

Please check and let me know. Src

@Abhay said in Compilation Error for Seeed XIAO nRF52840 Sense in Arduino IDE on macOS:

Seeed nRF52 mbed-enabled Boards: 2.9.2
Seeed nRF52 Boards: 1.1.8

@Abhay, are you getting the error while selecting both boards? You can also try using "Seeed nRF52 Boards: 1.1.8".

Since it's nRF series can you try to install the - adafruit-nrfutil pip package and see!

also try to install - Adafruit Feather nRF52 using board manager and check again.

@Vishnuraj2003 Are you able to fix it?

Hi @PumpedMedusa, The rage is depends on the Antenna and how much TX power you have.

To choose antenna, first you need figure out - where your nodes will be, take a look at the below image. The antenna act like a "torch" if you have more dbi that mean it's focus will be increase and it can reach more distance but the angle it have it less, like a laser.

also, obstacle such as buildings, tress and mountains will affect the signal and deplete it.

So, answer for you question - What is the best LoRa module to use for long distance network? - It's really depends on where you planning to put the nodes and how high you putting the gateway. Let me know know your thoughts.

@Parves-DOMINO Did you able to solve the issue?

@Parves-DOMINO Are you still facing the issue?
