Frequently asked questions
What is the price of ESP-12S WiFi Module ESP8266 Serial UART with AT Firmware in Egypt?
ESP-12S WiFi Module ESP8266 Serial UART with AT Firmware currently costs 170 EGP in Egypt.
Where can I buy ESP-12S WiFi Module ESP8266 Serial UART with AT Firmware in Egypt?
ESP-12S WiFi Module ESP8266 Serial UART with AT Firmware is available from Makers Electronics. Compare the offers above to find the best price.
How do I connect the ESP-12S to a microcontroller?
Connect TX and RX through UART. The module operates at 3.3 V logic, so do not feed it 5 V logic signals directly; use a level shifter or divider.
Do I need a USB-to-serial adapter to program it?
Yes. A 3.3 V USB-to-TTL adapter is typically used to send AT commands or upload firmware. Flashing usually requires holding GPIO0 low during reset, as described in the module's datasheet.
