LOLIN C3 Pico is a tiny ESP32-C3 board with battery charging support

LOLIN C3 Pico is a tiny (25.4×25.4mm) ESP32-C3 RISC-V board with 2.4 GHz WiFi and Bluetooth Low Energy connectivity, a few I/Os, and LiPo battery support including charging circuitry. I tend to like Wemos/LOLIN boards, because of their small form factor, support for equally tiny shields, and low price. The LOLIN C3 Pico is no exception, and even adds a few features such as an RGB LED, an I2C connector, and support for battery power and charging. LOLIN C3 Pico specifications: SoC – Espressif Systems ESP32-C3FH4 single-core 32-bit RISC-V (RV32IMC) microcontroller up to 160 MHz with 400 KB SRAM, 4MB Flash Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE (in SoC) Expansion headers 2x 8-pin headers with up to 12x GPIO, ADC, I2C, SPI, UART (3.3V I/O voltage) LOLIN I2C port USB – 1x Type-C USB for 5V power and programming Misc – Reset button and user button, […]

Google KataOS – A secure OS for embedded systems written in Rust (mostly)

Google Research has been working on its own Rust-based operating system called KataOS and designed to secure embedded systems that run Machine Learning (ML) applications. There has been a lot of talk about the Rust programming language in recent times, since it offers about the same level of performance as C programming but helps programmers write more secure code with built-in prevention against buffer overflows for instance. It has gained a lot of traction over the years, and Linux 6.1 will be the first kernel release to include Rust code. Google Research noticed that system security is often treated as a feature that can be added to existing systems either by software or an extra security chip. But in a world, where more and more of our private data is exposed to the world through the Internet, it is not good enough, so the company developed KataOS open-source, secure operating […]
