ROCK Pi Summer updates 2019

Dear ROCK Pi community,

About half an year ago, we introduced the first ROCK Pi 4 and we get a lot of feedback from different customers since then. We appreciate all the suggestions, contribution and criticism from the community. Now we are very excited to annouce the recent work from Radxa Team that you might be interested.

1. ROCK PI V1.4

We are happy to announce the minor hardware updates for ROCK Pi 4. The updates fixes some outstanding issues from the current ROCK Pi 4 users and also includes some minor improvements.

The major update that many users care about and even the main reason they buy ROCK Pi 4 is the NVMe support. ROCK Pi 4 model A is the lowest cost SBC you can buy with NVMe support on the market. We have now included a 4MB SPI flash on the new v1.4 boards. We have reduced the size of the image so 4MB flash can just include the first stage loader, u-boot and trust image. To support SPI directly boot into NVMe. We ported the RK3399 PCIe driver to u-boot and enabled the boot chain. Android is also supported for NVMe booting, which will come in later release.

Other minor changes includes:

4MB SPI flash soldered by default, on both model A and model B
NVMe booting from SPI is supported
User led changed from red to blue to avoid blink confusion
Wifi/BT adds external antenna support
Headphone connector improvement, with through hole legs for strengthened mounting
Changes the USB3 OTG label to simple L/H for Host/Device

2. ROCK Pi PoE HAT

The ROCK Pi PoE HAT is the accessory many users been waiting long. It takes so long time because we have completed re-designed the it after the first batch of prototypes sent out to some community users for testing. The new ROCK Pi PoE HAT looks cleaner by hiding the big transistor in the bottom. Optimized circuit plus the new added fan helps reducing the temperature, it drops from the peak 100°C to now below 40°C.

802.3 AT up to 23W
5V output on the GPIO power PIN
PWM control FAN up to 12000RPM
Temperature sensor on HAT for fan control
Optional 40PIN GPIO exported with pass through 40PIN header
Compatible with ROCK Pi 4 model B and Raspberry Pi 3B+

We provide a debian pacakge `rockpi4-poe` with service for automatically adjust the fan speed by temperature which you can install from Radxa APT.

3. USB3 eMMC reader

The eMMC reader is another accessory we designed for ourselves and the developers who need to write images on eMMC module freqently. It's just fast and reduces the image writing time a lot, much more handy than the eMMC to uSD adapter.

High speed USB3.1 Gen2 GL3227E controller
Support eMMC HS400 mode
Dual mount for eMMC module
Support ROCK Pi eMMC modules up to 128GB
Compatible with Odroid/PINE64 eMMC module
Support Linux/Windos/MacOS
Support GPT partition table and firmware

Real life usage example:

time  sh -c 'sudo dd if=rockpi4b-ubuntu-bionic-minimal-20190104_2101-gpt.img of=/dev/sdd bs=4M status=progress && sync'

4. ROCK Pi S

ROCK Pi S is the new little board of ROCK Pi family for the IoT and Audio applications. We designed it based on the new Rockchip RK3308 processor. We like the RK3308 very much because it's a low cost 64bit processor capable of running Linux with a lot of potentials. The features for ROCK Pi S includes:

RK3308, quad A35 64bits processor with built-in VAD
256/512MB RAM up to 1178Mbps
USB 2.0 OTG(type C) + USB 2.0 HOST(type A)
100MB ethernet, optional PoE(additional HAT requried)
802.11 b/g/n wifi + BT 4.0(rtl8723DS) with external antenna
26PIN Pi GPIO header + 26PIN voice/audio header
uSD card for OS storage media, optional 1/2/4/8Gbit on board NAND storage for cost saving
Size: 1.5inch square
Starting from 9.9USD with 256M ram

The first batch of ROCK Pi S are tested and proves working all well. We still have some samples in the office. Debian and buildroot is currently supported on ROCK Pi S. If you are intested in developing on ROCK Pi S or want to evaluate it for your project. You can contact us.
