Hi everyone,
As many of you may have already heard, Shanghai is currently undergoing a major lockdown due to COVID-19. In the midst of this lockdown, we received our production wafers of ESP32-C2, and proceeded with verification. Quarantine rules have caused us some logistics problems, but gradually we managed to find solutions and go ahead with ramping up the design and production of this chip. Also, thanks to Espressifers from Brazil, the Czech Republic, India and Singapore, the integration of ESP32-C2 into ESP-IDF and ESP-RainMaker continues at full speed.
ESP32-C2 is a combo Wi-Fi 4 + Bluetooth 5 ( LE) chip that was conceived during last year’s semiconductor supply shortages which -to a certain extent- persist even today. Hence, one of the most important goals for us in creating this chip was to reduce its silicon area and the flash size requirement. Thus, after almost a year of preparations, the resulting chip targets simple, high-volume, low-data-rate, IoT applications, such as smart plugs and light bulbs.
ESP32-C2 is a chip in a 4mm x 4mm package , with 272 kB of memory . It runs frameworks, such as ESP-Jumpstart and ESP RainMaker® , while it also runs ESP-IDF . ESP-IDF is Espressif’s open-source, real-time operating system for embedded IoT devices, which has been trusted by users across the whole wide world. It is supported by Espressif and the community for all ESP32 chips. The ROM code of ESP32-C2 is optimized, as it reduces the need for flash.
Thus, if you need a small, simple and cheap SoC that is able to provide your application with robust connectivity, ESP32-C2 is the way to go.Besides, ESP32-C2 also continues the tradition of Espressif’s excellent security, having such features as secure boot and flash encryption, while also providing hardware root-of-trust for any applications.

Introducing the ESP USB Bridge
The ESP USB Bridge is an ESP-IDF project utilizing ESP32-S2 or ESP32-S3 to create a link between a computer and a target microcontroller. It can serve as a replacement for USB-to-UART chips, e.g. CP210x.
AnalogLamb’s Version of ESP32-S3 Offers a 2 MP Camera, a Mic, and Two LCDs
AnalogLamb’s Maple Eye ESP32-S3 is a Wi-Fi-and-Bluetooth dev board based on Espressif’s ESP32-S3dual-core Xtensa LX7 microcontroller. Additionally, it is equipped with one 2MP camera, one microphone, and two LCDs placed on each side of the board.
