Single-core ARM -A7 32-bit core, integrated with NEON and FPU Built-in Rockchip's self-developed 4th generation NPU, with high computing precision, supports int4, int8, int16 mixed quantization, of which int8 computing power is 0.5TOPS, int4 computing power can reach 1.0TOPS Built-in self-developed 1st generation ISP3.2, supports 5 million pixels, supports HDR, WDR, multi-level noise reduction and other image enhancement and correction algorithms With powerful encoding performance, supports intelligent encoding, adaptively saves bitstream according to the scene, and saves 50% bitrate compared to conventional mode The above makes the picture not only high-definition but also smaller in size Built-in 16-bit DRAM DDR3L can maintain demanding memory bandwidth For Ultra (without WI-FI module) (8GB EMMC) Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use. Colour:Black Material: PCB Package Contents: 1x Development Board Only 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. The measurement allowed error is +/- 1-3cm.
