ESP-01S Wi-Fi Development Board - ESP8266
€3.50
- Ex Tax: €2.89
- Brand: Brandless
- Product Code: ESP01S
- Availability: In Stock
A super small module with Wi-Fi at a very low price. Ideal for IoT projects where you only need a few GPIO pins. This module is also ideal for adding Wi-Fi to other microcontrollers (without Wi-Fi).
Compared to the standard ESP-01, this ‘S’ version has 1MB flash memory instead of 512kB. In addition, this version has some improvements on the PCB.
Note: This module does not have a USB to serial converter. This means you will need a programmer to program this module with your computer via, for example, the Arduino IDE. Click on the following link to order an ESP-01S programmer: ESP-01S Programmer.
