Espressif is company designing low cost wireless WIFI solutions.

Their ESP8266 chip was among the first low cost WiFi IC and became popular choice for many makers and creative people who used it to add Internet connectivity to their designs. The integration and support in Arduino IDE makes programming even simpler.

The ESP32 chip that came after has WiFi and BLE connectivity, but also supports wired Ethernet connection, making it perfect for IoT applications. We provide range of development boards for both ESP8266 and ESP32.

The company further developed its portfolio by adding ESP32-S2 (with focus on WIFI), ESP32-S3, ESP32-C3 (RISC-V architecture), and ESP32-C6 (RISC-V with 2.4GHz WIFI 6 and BT LE 5.3). Olimex has designed development boards with ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 too. You can find a comparison table of some of the different ESP32 chips in the document here
