Orange Pi Compute Module 4 – A low-cost Rockchip RK3566-powered alternative to Raspberry Pi CM4

Orange Pi Compute Module 4

Orange Pi Compute Module 4 is a system-on-module mechanically and electrically compatible with the Raspberry Pi CM4, but powered by a Rockchip RK3566 quad-core Arm Cortex-A55 AI processor just like the Radxa CM3 introduced a few years ago, or more recently the Banana Pi BPI-CM2 (RK3568). The new module, also called Orange Pi CM4 for shorts, comes with 1GB to 8GB RAM, 8GB to 128GB eMMC flash, and an optional 128/256MBit SPI flash, as well as a Gigabit Ethernet PHY and on-board WiFi 5 and Bluetooth 5.0. It comes with the two 100-pin high-density connectors found on the Raspberry Pi CM4, and a smaller 24-pin connector for extra I/Os. Orange Pi Compute Module 4 specifications: SoC – Rockchip RK3566 quad-core Arm Cortex-A55 processor @ 1.8 GHz with Arm Mali-G52 2EE GPU, 0.8 TOPS AI accelerator, 4Kp60 H.265/H.264/VP9 video decoding, 1080p100f H.265/H.264 video encoding System Memory – 1GB, 2GB, 4GB, or […]

Orange Pi 3B – A Rockchip RK3566 SBC with an M.2 NVMe/SATA SSD socket, up to 8GB RAM

Orange Pi 3B

Orange Pi 3B is a new Rockchip RK3566 SBC that’s like a supercharged Raspberry Pi 3B board with the same form factor, but with a faster processor, up to 8GB RAM, and support for multiple storage options with a microSD card slot, an eMMC flash socket, an M.2 Key-M socket for NVMe (PCIe 2.1) or SATA III SSDs, as well as an SPI flash that should enable features like network boot. The board also features HDMI 2.0 and eDP display intefaces, a Gigabit Ethernet port, a WiFI 5 and Bluetooth 5.0 wireless module, four USB ports, MIPI DSI and CSI connector, and the 40-pin Raspberry Pi GPIO header. It’s powered through a USB-C port taking 5V instead of the micro USB port found in the Raspberry Pi 3B. Orange Pi 3B specifications: SoC – Rockchip RK3566 CPU – Quad-core Cortex-A55 processor @ up to 1.8 GHz GPU – Arm Mali-G52 […]

CHIPSEA CST85F01 480 MHz Cortex-M4 MCU supports dual-band WiFi 6 and Bluetooth 5.0 LE

Dual-band WiFi 6 IoT module

CHIPSEA CST85F01 is an Arm Cortex-M4F microcontroller clocked at up to 480 MHz and designed for IoT applications with dual-band (2.4/5.0 GHz) WiFi 6 with TWT (Target Wake Time) support, Bluetooth 5.0 LE, and a range of I/Os. Following the recent availability of 2.4 GHz WiFi 6 IoT chips such as Espressif Systems ESP32-C6 and Bouffalo Lab BL616, CHIPSEA CST85F01 offers an alternative with dual-band WiFi 6 connectivity while we are waiting for the launch of the ESP32-C5 RISC-V microcontroller. CST85F01 specifications: CPU core – Arm Cortex-M4F CPU with MPU and FPU @ up to 480 MHz Memory – 992 KB SRAM, SDR/DDR PSRAM interfaces Storage – 752 KB ROM, 8 Mbit to 128 Mbit flash WiFi features 2.4GHz/5GHz Wi-Fi 6 Data rates up to 286.8 Mbps (Tx) and 229.4 Mbps (Rx) with 20/40 MHz bandwidth Rx sensitivity – -98dBm in 11b mode, -93.5dBm in MCS0 HT20 mode Tx power […]
