Radxa, in collaboration with Rockchip’s Toybrick division, began sampling the new community-supported SBC built around Rockchip RK3568 with NPU. ROCK 3A is basically a little brother of ROCK Pi 4, with some improvements from the experience on ROCK Pi 4, the main features are:
- RK3568 based, Quad A55 up to 2GHz, Mali G52 GPU, 0.8T NPU
- pluggable eMMC module, 2/4/8GB LPDDR4 3200MT/s, dram controller frequency up to 1560MHz
- QC/PD power support, with a new generation QC/PD protocol IC
- Two USB2 same as ROCK Pi 4, two USB3(1x OTG+1x HOST), the two USB3 can be configured in SATA mode with a SATA breakout cable
- GbE with PoE support
- M.2 M key for NVMe with PCIe 3.0 x2 lanes
- M.2 E key for connectivity with PCIe 2.0 x1/SDIO/UART, support WiFi 6 cards
- 1x MIPI DSI, 1x MIPI CSI, compatible with ROCK Pi 4
- 40P GPIO mostly compatible with ROCK Pi 4
ROCK 3A will run Debian 10, maintained by the Toybrick team. Other community distributions will also be supported too. Early samples(few) for developers are ready. A larger batch will be available in late August 2021. As for an alternative, Raspberry Pi Compute Module 4 based devices are ready for orders.
ModBerry 500 CM4 an ultimate solution for IoT monitoring
TECHBASE’s ModBerry industrial computer series has received an update to Compute Module 4 and is available for orders. TECHBASE is leading manufacturer of Industrial Raspberry Pi and Industrial Compute Module solutions. ModBerry 500 series is fully compatible with all releases of Compute Module from Rasbperry Pi foundation.
Main features of updated device are:
- up to 4x faster eMMC Flash with up to 32GB storage
- up to 2x faster performance of CPU appllications than previous CM3 version
- up to 8x more RAM (8GB LPDDR4-3200)
- 1Gbit Ethernet interface
- PCI 2.0 card support for NVMe SSD drive (via M.2)
- two PCIe support for wireless modem solutions, i.e. LTE/5G modems
Raspberry Pi Compute Module 4 world premiere
Few days ago, Raspberry Foundation announced new member of its family, a Rasbperry Pi Compute Module 4. It’s quite obvious, even from the first look, that the new module is very different from its predecessors. Main difference is a new form factor, leaving DDR2 SODIMM in the past.
The same 64-bit quad-core BCM2711 application processor as in Raspberry Pi 4B, the Compute Module 4 brings higher performance: faster CPU cores, better multimedia, more interfacing capabilities, and, for the first time, a choice of RAM densities and a wireless Wi-Fi and Bluetooth connectivity options.
Compute Module 4 comes in 32 variants. Lite, as always, offers no eMMC memory, a and standard versions come with up to 8GB RAM, 32 eMMC Flash and wireless modem.
New features of Compute Module 4
- 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU as in Raspberry Pi 4 version B
- 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM
- 8GB, 16GB or 32GB eMMC Flash storage for Standard version, Lite version without eMMC
- Optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0
- Single-lane PCI Express 2.0 interface
- Gigabit Ethernet PHY with IEEE 1588 support
- Dual HDMI interfaces, at resolutions up to 4K
- 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI
