“ESP32-C3-0.42LCD” is a tiny WiFi & BLE IoT board with 0.42-inch display, Qwiic connector

ESP32-C3-0.42LCD

01Space “ESP32-C3-0.42LCD” is a small (23.5 x 18 mm) board equipped with ESP32-C3 RISC-V WiFi and Bluetooth microcontroller, a 0.42-inch display, and a Qwicc I2C connector to easily add modules such as sensors. The first time I saw it, the form factor immediately reminded me of the nRF52840-based XIAO BLE Sense board I just used to test Edge Impulse machine learning framework. Both boards should have similar use cases, but XIAO BLE Sense includes a 6-axis IMU sensor, and I had to connect an OLED display, while the ESP32-C3 board already integrates a display, and I would have had to connect an external Qwicc module with an accelerometer. ESP32-C3-0.42LCD specifications: SoC – ESP32-C3FH4 SoC with RISC-V core @ 160 MHz, 4MB flash, 2.4GHz Wi-Fi, and Bluetooth 5 LE with Long-Range support Ceramic antenna Display – 0.42-inch LCD USB – 1x USB Type-C port for power and programming Expansion Qwiic I2C connector […]

Embedded World 2022 – June 21-23 – Virtual Schedule

Embedded World 2022

Embedded World 2020 was a lonely affair with many companies canceling attendance due to COVID-19, and Embedded World 2021 took place online only. But Embedded World is back to Nuremberg, Germany in 2022 albeit with the event moved from the traditional month of February to June 21-23. Embedded systems companies and those that service them will showcase their latest solution at their respective booths, and there will be a conference with talks and classes during the three-day event. The programme is up, so I made my own little Embedded World 2022 virtual schedule as there may be a few things to learn, even though I won’t be attending. Tuesday, June 21, 2022 10:00 – 13:00 – Rust, a Safe Language for Low-level Programming Rust is a relatively new language in the area of systems and low-level programming. Its main goals are performance, correctness, safety, and productivity. While still ~70% of […]
