ESP32 Arduino 2.0.0 release adds ESP32-C3 and ESP32-S2 support

As just noted in my article about LILYGO T-32C3 module, the ESP32 Arduino 2.0.0 release happened a few days ago adding ESP32-C3 and ESP32-S2 support to the Arduino IDE. But the news probably warrants its own post and it is a major release of the Arduino code for ESP32 that also includes other new features and changes namely: Upload over USB CDC. Support for the KSZ8081 Ethernet PHY. LittleFS update for partition label and multiple partitions. Added support for RainMaker. BLE 5 features for ESP32-C3 (ESP32-S3 ready). ESPTOOL update. Added 802.11mc WiFi RTT FTM (Fine Time Measurement) support. Online Documentation added (somehow it requires a login to Readthedocs). USB MSC (Mass Storage) and HID support (ESP32-S2 only). UART refactoring (SerialHardware). New examples, boards added, bugs fixed. You can find a more detailed changelog, including the exact files changes in the source code, on Github. If we want to give it […]

PICO DSP is an Arduino compatible ESP32 development board for audio and DSP applications (Crowdfunding)

ESP32 audio development boards have been around ever since ESP32 boards were introduced starting with Espressif Systems’ own “ESP32-LyraTD-MSC Audio Mic HDK“, and now ESP32 hardware and software have been certified for Amazon Alexa Voice Services. PICO DSP is another ESP32 development board for audio and digital signage processing (DSP) applications. Equipped with a Wolfson WM9878 stereo audio codec, the breadboard-friendly, Arduino compatible board includes two MEMS microphones, audio in and out jacks, a speaker header, plus other audio signals routed to a GPIO header. PICO DSP specifications: SiP – Espressif ESP32-PICO-D4 system-in-package with ESP32 dual-core WiFi 4 & BLE processor, 4MB SPI flash External storage/memory Original Edition – External 64 MB pseudo-static (PSRAM) chip, of which up to 8 MB is currently supported by ESP-IDF. Strawberry Edition – 16 MB of external NOR flash (note: the internal 4MB SPI flash will not be usable after selecting the NOR flash […]

ESP32-C3 WiFi & BLE RISC-V processor to launch at ESP8266 price

[Update December 2020: While we first reported ESP32-C3 would be pin-to-pin compatible to ESP8266 based on the tweet mentioned in the post, the datasheets show both are clearly not pin-to-pin compatible, and instead it looks like the goal is to provide pin-to-pin compatible modules] When we reported about ESP32-S2-MINI modules last September, we also noted Espressif teased us with ESP32-S3 and ESP32-C3 with close to no details. ESP32-S3 is expected to be a multi-core WiFI & Bluetooth processor with AI instructions/accelerator, but there were no details about ESP32-C3 at all, and we only found out it would be a RISC-V processor several weeks ago. But Twitter user Johnny Wu posted a screenshot in Chinese and its translation claiming ESP32-C3 was finally released by Espressif Systems. [Update: The datasheet has been released. See comments.] ESP32-C3 WiSoC is pin to pin compatible with ESP8266, works with ESP32 development framework (e.g. ESP-IDF), supports […]
