Features: 1. The for Radxa Zero adopts the for Zero W form factor,2. However, due to the use of the Amlogic S905Y2 quad-core Cortex-A53 processor with a main frequency of up to 2.0 GHz,3. Higher performance, which Radxa says is equivalent to about 70% of the CPU performance for .4. The tiny Arm Linux board is equipped with up to 4GB of RAM, 16GB of eMMC flash memory, and an AP6212 or AP6256 wireless module.5. Plus all the ports for the Zero W, but with a twist, the mini -compatible port is replaced by a --compatible port, and the USB-C port is used instead of the -USB port.Specification:model:LPDDR4 RAM 1GB, WIFI4/BLE4, no eMMCProduct Details:-Amlogic S905Y2 64-bit quad-core processor-Quad Cortex- -A53, frequency 1.8Ghz, 12nmCPU: Mali G31 MP2 GPU, supports OpenGL ES 1.1 /2.0 /3.1 /3.2, Vulkan 1.1, Open 1.1 1.2, 2.0 full profileMemory LPDDR4: 64bit channel LPDDR4@3200Mb/sWifi/BT Antenna: Wifi/BT with external antenna support, different models provide WIFI4/BLE4 and WIFI4/BLE5 Storage eMMC 5.1: Soldered high-performance eMMC 5.1 with 8GB/ 16GB capacity-SD card: USD slot supports up to 128G uSD cardDisplay_ --compatible: -compatible 2.1, 4K@60 HDRPeripherals: HD codec H265/VP9 decode 4Kx2K@60USB 3.0 Type-C HOST x1: USB 3.0 HOST; dedicated USB3.0 channelUSB2.0 Type-C OTG x1: USB 2.0 OTGNetwork (depending on model)---Wireless 802.11 abgn wifi 2.4GHz, Bluetooth 4.2---Wireless 802.11 ac wifi 2.4/ 5GHz, Bluetooth 5.0IO 40-pin expansion header:- 1 x UART- 2 x SPI Bus- 2 x I2C Bus- 1 x PCM/I2S- 1 x SPDIF- 1 x PWM- 1 x ADC- 1 x GPIO- 2 x 5V DC in- 2 x 3.3V pinsProduct size:65 x 30 x 5mm (same as zero W for )Material: PCB+Metalcolour: greenPackage Contents:1 x for Radxa Zero development boardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
