When the ESP8266 was first announced to the world, we were shocked that someone was able to make a cheap, accessible UART to WiFi bridge. Until we get some spectrum opened up and better hardware, this ...
Este código lê os pulsos de um sensor de encoder usando um ESP8266, conta esses pulsos em uma interrupção e calcula a velocidade de rotação em RPM a cada segundo. A velocidade calculada é então ...
We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...
The ESP Offline Programmer is an ESP32 board with a microSD card slot designed to flash the firmware to other ESP32 or ESP8266 modules without a PC. You’ll still need one to copy the firmware to a ...
