Si4735 TTGO T-Dispray ESP32 radio receiver - Updated
I updated my Si4735-D60 FM/AM/SW with SSB mode radio receiver which is controlled by TTGO T-Display ESP32 that I introduced before ().
1) Arduino sketch by Ralph Xavier was updated with his new version 4.1.
2) Small speaker was implemented.
3) PAM8403 audio amplifier unit was implemented.
4) Audio mute circuit to prevent loud popping of the speaker was implemented.
I recommend you assembling your own receiver like in this video, as it requires only a few parts to be placed on a breadboard and wired, it works without the need for fine tuning, you can understand how it works, and it is cheaper than buying a finished product.
