After we reported about ESP32-S2-MINI modules ideal September, we also worthy Espressif teased us with ESP32-S3 and ESP32-C3 with with regards to no tiny print. ESP32-S3 is anticipated to be a multi-core WiFI & Bluetooth processor with AI directions/accelerator, however there hang been no tiny print about ESP32-C3 at all, and we handiest came upon out it may per chance possibly per chance be a RISC-V processor several weeks prior to now.
But Twitter particular person Johnny Wu posted a screenshot in Chinese and its translation claiming ESP32-C3 modified into lastly released by Espressif Systems. [Update: The datasheet has been released. See comments.]
ESP32-C3 WiSoC is pin to pin take care of minded with ESP8266, works with ESP32 building framework (e.g. ESP-IDF), supports Wi-Fi & Bluetooth LE 5.0 connectivity, and integrates 400KB SRAM & 384KB ROM. It components a single32-bit RISC-V (RV32IMC) core @ 160 MHz, and bask in as dinky as 5uA in deep sleep mode. Pricing will also be such as ESP8266.
I may per chance possibly also no longer get any knowledge on Espressif Systems yet, nor grand on other sources, and the text above appears to reach support from a publish on Xueqiu, and the actual person also reported Espressif raised funds to fabricate a WiFi 6 FEM (Front-finish module). Alternatively, the news confirms just some of the pointers on hand in the source code for esptool, ESP-IDF, and openOCD when buying for “esp32c3” string, just a few of which is listed in a thread on ESP32.com forums.
If the tips is pleasurable that technique ESP32-C3 based RISC-V WiFi and Bluetooth modules such as ESP-01 must peaceable soon be on hand on the marketplace for spherical $1.
Attributable to Arnaud for the tip.
