AI Gateway combines Raspberry Pi Compute Module 4 with Google Coral Edge TPU

Techbase quickly unveiled an update to their Modberry industrial controllers with Modberry 500 CM4 DIN Rail computer as soon as Raspberry Pi Compute Module 4 was launched. The company has now introduced another Raspberry Pi CM4 based product with ModBerry AI GATEWAY 9500-CM4 gateway combining the Broadcom BCM2711C0 system-on-module to Google Edge TPU to cater to applications leveraging AI acceleration. ModBerry AI GATEWAY 9500-CM4 preliminary specifications: SoM – Raspberry Pi Compute Module 4 AI accelerator – Google Coral Edge TPU module with up to 4 TOPS connected over the RPi CM4’s PCIe interface Peripherals (customizable as needed) USB, HDMI, and Ethernet. Serial RS-232/485 ports Digital and analog I/Os with or without opto-isolation Relays, 1-Wire, CAN bus, M-Bus Master and Slave PCIe modules for wireless support Cellular – 4G/LTE and 5G modem, interchangeable with Coral TPU, plus on-board eSIM LPWAN – NB-IoT, LoRa, Sigfox, Wireless M-Bus ZigBee Additional Wi-Fi/Bluetooth interface or […]

STMicro launches cheaper STM32WB30 and STM32WB35 Bluetooth LE & Zigbee MCUs

STMicro introduced the first wireless STM32 microcontrollers in 2018 with STM32WB Cortex-M4/M0+ MCU family equipped with Bluetooth 5.0 and 802.15.4 radios, and they followed earlier this year with STM32WL Cortex-M LoRa SoC. The company has not just announced yet another wireless STM32 family but instead added the more affordable STM32WB35 and STM32WB30 chips that can be obtained for under $2 in quantities. The new STM32WB microcontroller enabled a low BOM cost thanks to their memory configuration. Specifically, STM32W30 comes with 256KB flash while STM32W35 features 512 KB flash, and both offer 96 KB of RAM. This compares to STM32WB55 will up to 1MB flash and 256KB of RAM. Apart from the lower memory and flash capacity, the new wireless MCUs have basically the same features as other members of the STM32WB family with 16-bit ADC, quad-SPI interface (STM32WB35 only), as well as Bluetooth Low Energy 5.0, Zigbee 3.0, and OpenThread […]
