Transmitting and Receiving messages through RF433 using Raspberry Pico

Ask QuestionAsked yesterdayActive yesterdayViewed 24 times1

I’m currently working in a new DIY project, where I need to send a message through RF from Raspberry Pico, and receive it in an other Raspberry Pico through RF. I have bought some common RF433 receivers and transmitters (see image below)

I’m using MicroPython.

I have searched Internet to find possible solutions, but didn’t manage to find one for Pico. Is it feasible?

Also, is there a library that I can use to send and receive messages through RF433?

Thank you in advance.

• 1(1) MX-05V is newbie firendly. (2) Arduino video tutorial, libraries, and demo code are easy to find. (3) Pico equivalent is not around, unfortunately. (4) Fortunately the code is not that complicated, so you can try to convert the Arcuino C++ code to Pico MicroPython (the other way around is more difficult, though). If you decided to use MX-05V, you might like to list the simple code and me or others might give a hint on how to convert it to python. PS, I once used use Arduino Decimilla 3V3 SPI RF12B and found it tricky to work with, But 5V MX-05Ｖ is much simpler. / to continue, … – tlfong01 23 hours ago   
• 1Thanks for your comment. I will try your proposal to convert Arduino library to RpiPico. Do you have any specific library recommendation? – Antifa 12 hours ago
• Ah, I need to first look at the datasheet, to make sure if my suggestion makes any sense. 433MHz Wireless Modules MX-05 _ HobbyComponents forum.hobbycomponents.com/viewtopic.php?t=1324 – tlfong01 12 hours ago   
• I randomly googled and found this library. Now I am checking it out. HCWireless Arduino Library for 433MHz Wireless Tx & Rx modules – HobbyComponents forum.hobbycomponents.com/viewtopic.php?f=58&t=2914 – tlfong01 12 hours ago   
• The HobbyComponents does not provide any MX-05V datasheet. Other shops seems to link another chip: components101.com/modules/433-mhz-rf-receiver-module. – tlfong01 11 hours ago

• OK. BTW, documentation is very good: airspayce.com/mikem/arduino/VirtualWire.pdf – tlfong01 15 secs ago   Edit
