Hello all,

Caution, I am a newbie to MCUs. I am looking for a low cost MCU board with Bluetooth for communication with mobile app. I have purchased NodeMCU which comes with onboard WiFi. However, I would like to talk to MCU via Bluetooth directly. If I use NodeMCU or ArduinoNano, I would have to purchase a separate Bluetooth module.

I did little research over the web but could not find anything significant. Hence, I am here! Please assist.

Regards,
Akif

 

TI has several of these. I’m assuming other manufacturers have them as well.
The cc2540 has a 8051
The cc2642 has an arm M4

I would caution that Ive used the cc 8051 series from TI before. There is a bit of a learning curve on this series to just get it up and running. It is not a good first microcontroller.

The arm controller does have a launchpad which should help speed up product development.

 

well there are some very decent board made up with bluetooth functionality. The feather family of boards from adafruit have a few selections with onboard bluetooth.

as an example. the chipset on that one is the nrf52840.

 

Telink TLSR8266F512 (RISC 32-bit MCU)

JDY-10 modules are sold on Aliexpress. I bought a couple and made a board. Now experiments are ahead.

 

Have a look at the Espressif range of products, modules and development boards, all with a ton of support and software. https://www.espressif.com/

 

Espressif has an ESP32-C3FH4 chip for about $ 1.50 (RISC-V MCU + Wi-Fi and Bluetooth).
