Renesas RA8D1 Arm Cortex-M85 SoC features LCD display interfaces, 2D graphics accelerator

Renesas RA8D1

Renesas RA8D1 is a new Arm Cortex-M85 microcontroller with graphics capabilities such as a 2D graphics accelerator and MIPI DSI and parallel RGB interfaces to connect an LCD that will make the chip suitable for HMI applications. Renesas introduced the world’s first Arm Cortex-M85 microcontroller with the RA8M1 just a few weeks ago, but the MCU has limited multimedia capabilities with just a 16-bit Capture Engine Unit (CEU) interface to connect a camera. The second member of the Renesas RA8 family fills this void with the RA8D1 microcontroller adding an LCD controller and a 2D graphics drawing engine on top of the CEU camera interface. Renesas RA8D1 specifications: MCU core – Arm Cortex-M85 clocked at 480 MHz with Helium MVE (M-Profile Vector Extension) with 32KB I/D caches, 12KB data flash Memory & Storage 1MB SRAM with TCM (128KB) 1MB to 2MB Flash memory 32-bit external SDRAM interface Display interfaces and […]

Youyeetoo X1 x86 SBC Review – Part 2: GPIO, UART, I2C, SPI, NFC, PoE module, and power consumption

Youyeetoo X1 GPIO review

The Youyeetoo X1 x86 single board computer (SBC) with an Intel Celeron N5105 Jasper Lake CPU differs from a typical Intel or AMD mini PC by its range of IOs including SPI, I2C, UART, NFC connectivity, and support for PoE module that you won’t find in a typical computer, and that’s what we will test in the second part of the X1 SBC review along with power consumption. The Youyeetoo X1 SBC is also different from Arm-based single board computers since we can just install any x86-compatible operating system by ourselves, and w don’t need to flash a board-specific image like we would do with Arm SBCs and peripherals such as SPI, I2C or UART may be or may not usable immediately due to lack of supported drivers. We’ve already installed Ubuntu 22.04 on the Youyeetoo X1 in the first part of the review, so in the second part, we’ll […]

Sparkfun launches cheaper no-code “DataLogger IoT” board compatible with Qwiic modules

Sparkfun DataLogger IoT

Last May, SparkFun introduced the “Datalogger IoT – 9DoF” no-code platform with support for over 50 Qwiic sensor modules and a built-in 9-axis IMU sensor and magnetometer. Taking into consideration that some users may not make use of the built-in sensors, the company decided to launch a cheaper version called the “DataLogger IoT” that can still get data from Qwiic sensor and GPS modules without any programming thanks to the “no-code” Arduino firmware preloaded on the ESP32-WROOM-32E module. SparkFun DataLogger IoT specifications: Wireless module – ESP32-WROOM-32E with: ESP32 dual-core microcontroller 4MB flash 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Storage – MicroSD card slot USB – 1x USB Type-C port for power and configuration via CH340C Expansion – 2x Qwicc I2C connectors for sensors and/or GPS module Misc Boot and Reset buttons Status and charging LED, WS2812 RGB LED Jumpers to enable/disable LEDs, I2C pull-up resistors, and […]
