@zainmuhammed Oh that's cool. Let me also take a look at the stability analysis of a drone and get back to you.

@alanbiju https://ardupilot.org/copter/ This is one of the best doc. the entire thing for drone building is available here. also next month, I will be releasing a doc on drone building from scratch.

@saheen_palayi Photon2 is now available at $ 17.95 on their official store page, soon it will be available on the Indian website. I was able to grab it once and will ping you once I received it.

@borncurious Okay got it. Yeah, Tez was really exciting in terms of how seamless it was. I really got astonished. when I got to know it was doing it over audio those days.

So, are you looking for any libraries to do it or any sample projects?

Hi @borncurious , For the industrial purpose you can go with Raspberry Pi compute modules, Take a look at the latest version CM4 - https://www.raspberrypi.com/products/compute-module-4/ , Which is designed for industrial usage and incorporates a quad-core ARM Cortex-A72 processor, dual video output, and a wide selection of other interfaces. Available in 32 variants, with a range of RAM and eMMC Flash options, and with or without wireless connectivity.

Other options are, boards like RockPi and Orange Pi boards which are similar to Raspberry similar model and specs but the price is a bit lower than the raspberry pi. Make sure to check the Interface and driver support that you need to incorporate into your project since these boards are not documented and maintained like the official raspberry pi as far as I know.

also, you can check Toradex System on Module.

@MakerGram 🤩🙌 Looking forward.

Thanks for sharing @salmanfaris

@Richu-Bini I'm not sure if this is the root cause but normally, you should add an RC delay on the EN pin. This is because the BOOT pin should reach 3.3V before the EN reaches 3.3V hence, the RC delay on the EN pin. A 10K resistor and a 1μF Cap should do it. Here's a sketch on how it should look like:

Here is the part in the datasheet of the WROOM32 that tells you to do it:

@Adithya-SM Can you confirm the I2C address is correct? You can use this I2C Scanner to program to find the correct address

// -------------------------------------- // i2c_scanner // // Modified from https://playground.arduino.cc/Main/I2cScanner/ // -------------------------------------- #include <Wire.h> // Set I2C bus to use: Wire, Wire1, etc. #define WIRE Wire void setup() { WIRE.begin(); Serial.begin(9600); while (!Serial) delay(10); Serial.println("\nI2C Scanner"); } void loop() { byte error, address; int nDevices; Serial.println("Scanning..."); nDevices = 0; for(address = 1; address < 127; address++ ) { // The i2c_scanner uses the return value of // the Write.endTransmisstion to see if // a device did acknowledge to the address. WIRE.beginTransmission(address); error = WIRE.endTransmission(); if (error == 0) { Serial.print("I2C device found at address 0x"); if (address<16) Serial.print("0"); Serial.print(address,HEX); Serial.println(" !"); nDevices++; } else if (error==4) { Serial.print("Unknown error at address 0x"); if (address<16) Serial.print("0"); Serial.println(address,HEX); } } if (nDevices == 0) Serial.println("No I2C devices found\n"); else Serial.println("done\n"); delay(5000); // wait 5 seconds for next scan }
