Forlinx has launched the OK1028A-C SBC, alongside a FET1028A-C module, which is designed based on Cortex -A72 featuring dual-core processor LS1028 A up to 1. 5G Hz. It features on-board 2GB DDR4 RAM and 8GB eMMC, can support 5 Gigabit Ethernet ports with TSN, 2 CAN-FD, USB3.0, UART, SPI, IIC, LVDS, TF card slot, SATA3.0, Headphone peripheral sources, and preserved with M.2 Key B for 5G module, mini PCIe for 4G module, and M.2 Key E for WiFi module. This is coming after Forlinx launched the headless OK1043A-C and OK1046A networking SBCs last year, which are powered by NXP’s quad-core, Cortex-A53 LS1043A, and quad -A72 LS1046A SoCs. However, the older SBCs do not enable video output, and you can only carry out configuration via a computer or laptop either through a UART interface or a web interface. To solve this problem, Forlinx released the new OK1028A-C which offers both a display interface and TSN (Time-Sensitive Networking).

The OK1028A-C is based on the FET1028A-C, and features 5x GbE ports with TSN, a microSD slot, USB 3.0 host port, 2x CAN-FD ports, SATA III with SATA power, and a UART debug DB9 port. It features an LVDS interface which enables a PWM backlight control and a headphone jack and speaker. The OK1028A-C also enables a mini-PCIe slot that supports an optional 5G module and a M.2 B-key slot which supports an optional 4G module, both with the help of a SIM card slot. Available also is an M.2 E-key module with PCIe Gen2 which supports an optional, dual-band WiFi module. If offers additional interfaces like JTAG, SPI, 3.3V UART, and 2x I2C. The board offers a 12V jack with power and reset switches, 2x programmable LEDs, and an RTC with battery. The OK1028A-C SBC runs Ubuntu 18.04 with Qt 5.9.9 with the development of HMI applications. The OK1028A-C can be applied to Industrial IoT, TSN, SD-WAN, 5G CPE, edge computing, gateway, IP-PBX, smart factory, information security, intelligent transport, power management,

The FET1028A-C module that drives the OK1028A-C SBC supports up to 5x 2.5GbE ports, as well as SerDes technology, but the SBC is limited to 5x 1GbE ports. Th is compared to up to 6x or 7x 1GbE ports on the OK1043A-C and OK1046A, respectively. Those earlier boards also feature a 10GbE port and the OK1046A adds a 10GbE SFP+ or SFP-GE cage. The FET1028A-C features a 4-port TSN switch with 2.5GbE support and also support for a fifth 2.5GbE port and a GbE port. Five of the GbE ports can be configured by SerDes with SATA III and 2x up to 8GT/s PCIe 3.0 in various combinations with SGMII and QSGMII Ethernet. The 65 x 42mm FET1028A-C module also features 2GB DDR4 and 8GB eMMC, and enables DP 1.3 and eDP 1.4 interfaces up to 4Kp60. Other features includes up to 2x USB 3.0, 2x CAN FD, 4x UART, 6x I2C, 6x I2S, 2x SPI, and SD 3.0. The module has an operating range of -40 to 85℃.
