Renesas RZ/T2H Cortex-A55/R52 industrial MPU and Dev Board support EtherCAT, PROFINET, and TSN

Renesas RZ T2H EVKIT

Renesas RZ/T2H industrial MPU is the most powerful member of its RZ/T2 series of real-time microprocessors. The MPU features four Arm Cortex-A55 CPUs for application tasks and two Cortex-R52 CPUs for real-time control. It supports 9-axis motor control with 3-phase PWM timers, delta-sigma interfaces, and encoder interfaces. It also supports Industrial Ethernet protocols like EtherCAT, PROFINET, and TSN. These features make it ideal for industrial applications such as industrial robots, PLCs, motion controllers, and CNC machines. Renesas launched the RZ/T2L single-core Arm Cortex-R52 MPU just last year, and before that, in 2022, they launched the RZ/T2M dual Arm Cortex-R52 MPU. The RZ/T2L was just a cost-down version of RZ/T2M with an EtherCAT controller, compared to those old controllers the latest RZ/T2H supports 9-axis motor control and compatibility with various industrial Ethernet protocols.

$20 ATOMIC Display Base is a low-cost HDMI display driver for M5Stack’s ESP32-based Atom IoT controllers

M5Stack ATOMIC Display Base (GW1NR)

M5Stack has recently launched the M5Stack ATOMIC Display Base, an HDMI display driver designed to emulate traditional SPI TFT-LCD data output using Gowin GW1NR-9C FPGA and a built-in LT8618SX RGB-to-HDMI chip and designed to work with the company’s Atom IoT controller family based on ESP32 wireless microcontrollers. The module supports up to 720p (1280×720) image output with a 24-bit color depth and has an average frame rate of 12–16 FPS. Additionally, it can be paired with ATOM series hosts for various memory and application needs. These features make this compact device suitable for industrial control displays, smart home information screens, educational and conference presentations, and remote monitoring displays. The only downside of this device is that it requires a display with adaptive resolution scaling to avoid compatibility issues.

Renesas RRH47000-EVK board integrates RRH47000 CO2 sensor with ±75 ppm accuracy, relative humidity and temperature sensors

Renesas RRH47000 CO2 sensor

Renesas has recently released the RRH47000-EVK evaluation board based on the RRH47000 CO2 sensor using non-dispersive infrared (NDIR) technology to measure CO2 levels accurately (±75 ppm typical) within the 0-5000 ppm range. The sensor also includes built-in sensors for relative humidity and temperature, operates at low power, and supports either UART or I2C interface to the host. These features make this device useful for applications like HVAC systems, industrial automation, building control, air quality monitors, home appliances, IoT devices, and agriculture. Previously we have written about the Sensirion SCD40 CO2 sensor which also uses NDIR to measure CO2 levels very accurately, while the Infineon PASCO2V15 CO2 sensor relies on photoacoustic spectroscopy (PAS) to detect CO2 levels. The Sensirion sensor can also measure humidity and temperature, but the Infineon sensor is designed to measure CO2 only.
