AFE-E420 – NXP i.MX 93 4″ Industrial SBC by Advantech

The AFE-E420 from Advantech is a feature-rich 4-inch single board computer designed for demanding industrial applications requiring extensive connectivity and robust performance. At its core is the NXP i.MX 93 processor featuring dual Arm Cortex-A55 cores operating at 1.70 GHz, paired with up to 2GB of LPDDR4x-3733 memory with inline ECC support for enhanced reliability. The integrated 16GB eMMC provides ample onboard storage, while expansion options include M.2 E-Key 2230 for WiFi modules, M.2 B-Key 3042 with Nano-SIM support for cellular connectivity, and an SD card slot for additional storage flexibility. Display connectivity is provided through single-channel LVDS supporting resolutions up to 1366×768 or 1280×800, with optional HDMI 1.3 output available by request for 1920×1080 resolution. The AFE-E420 excels in communication capabilities with dual Gigabit Ethernet ports using Realtek RTL8211 PHY controllers, six RS-232/422/485 serial ports with isolation on COM5 and COM6, and four CAN-FD interfaces with isolation on CAN1 and CAN2. A unique feature is the dual QCA7006 Power Line Communication controllers with Control Pilot functionality including PWM and ADC, making this board particularly suitable for EV charging infrastructure. Additional I/O includes 16-bit GPIO, dual I2C buses, four-channel RTD input compatible with PT100/PT1000 sensors, and comprehensive audio support with Line-in, Line-out, MIC, and a 2.5W stereo amplifier. The board operates from 12-24V DC input with AT/ATX power management and features an extended temperature range of -40 to 85°C for LVDS configurations, along with CE and FCC Class B certifications. The compact 165x115mm form factor and support for Yocto BSP make the AFE-E420 ideal for industrial automation, energy management systems, smart grid applications, and EV charging stations.
