Originally published on hackaday.com by Bryan Cockfield on 14 September 2023
In today’s era of music streaming and podcasts, having a functional radio can still prove invaluable, particularly in emergency situations when internet access may be disrupted. For our PiShop readers seeking the most compact FM radio solution, a DIY project utilizing an ESP32 offers a compelling option.
This ESP32-based radio project incorporates a TTGO T-Display board with a 1.14-inch ST7789V IPS panel, alongside the TEA5767 chip for FM radio signal processing. Programmed by Volos Projects, the ESP32 stores and allows toggling between five preset radio channels using two buttons located at the device’s bottom. The radio also includes circuitry to facilitate audio output to headphones or a stereo system.
One notable feature of this project is its open-source nature, which enables enthusiasts to customize and enhance its functionality. Modifications could include adding seek/tune functionality to complement the preset channel system, offering a versatile and adaptable radio solution for a variety of use cases.
Why not take this project a step further by making an Open-Source Cell Phone Based on ESP32?
