Project Overview 

Special Note

This project will come completely soldered but you still need to program it to make it work with your Payment Gateway. This project also requires a lot of pre configurations like,

  • Creating Business account for PayTM/Razorpay
  • Creating and Configuring Pipedream account for Custom webhooks URL
  • Creating and Configuring Adafruit IO account
  • Programming ESp32C3 board with all your credentials

So make sure you have enough technical knowledge to do all these things as we won’t be able to support you by guiding at each and every step. We still have our detailed tutorial videos available on YouTube that will help you with all the steps mentioned above.


Note:- This is a DIY project and not a commercial product(It’s still shipped after completely testing from our end). Its main purpose is to educate people about how the Payment Sound Box actually works. We don’t provide any kind of warranty or guarantee on this project.
