Powerful Processor: The Mini PC is powered by a Core i5-8265U CPU (6M cache), which delivers laptop-grade performance in an efficient. Its 4 cores and 8 threads ensure smooth multitasking, while a turbo boost frequency of up to 3.9GHz easily handles demanding workloads like spreadsheet analysis and photo editing. With a low 15W TDP, it operates quietly and saves energy. The system also supports Linux and a wide range of essential software Dual Ports GbE LAN: The fanless industrial computer features 2 x Gigabit Ethernet RJ45 ports(i219LM-i5 8265U, i210AT-J6412&i5 8265U, 8111H-J6412 )with independent dual-network control, this solution reduces latency and enhances data transmission efficiency. It is ideal for high-load scenarios such as video editing and remote work, while also delivering stable performance during extended operation Flexible Storage & Expansion: SJRC industrial PC features 1xDDR4 SODIMM slot, supporting single-channel memory of up to 32GB. The memory speed is 2400 MT/s with the i5-8265U CUP and 3200 MT/s with the J6412. It provides 1XM.2 2280 slot (for the i5-8265U) that supports both SATA and NVMe SSDs, with an optional 1 x 2.5-inch drive bay. For expansion, it offers 1 x M.2 2230 E-Key slot and 1 x M.2 3052 B-Key slot for 4G/5G modules, along with a dedicated SIM card slot Fanless Design & Noise-free: The fanless mini desktop PC adopts a fanless and a sealed aluminum alloy case design, the aluminum alloy structure helps your computer dissipate heat efficiently. It saves electricity bills and eliminates noise. Low power, can be used for 24*7 hours. The most important thing is to prevent dust from entering the inside of the machine and prolong the life of the computer Rich I/O: Fanless PC featuring 6xCOM RS232/RS485/422 ports, 1xHD Display, Realtek ALC897 HD Audio with Line-out and MIC-in, compatible with 4Ω 3W / 8Ω 2W external speakers. 4×USB 3.2 ports(i5-8265U), 2xUSB3.2(J6412), 2xUSB2.0(J6412), optional 16-channel GPIO, pre-definable locking terminal block (default: Remote SW). Wide-range 9–36V DC power input with both locking type and terminal locking connectors
