- Built in 512KB SRAM and 384KB ROM, with onboard 16MB Flash and 8MB PSRAM
- Onboard 4.3inch capacitive touch display, 800×480 resolution, 65K color
- Supports capacitive touch control via I2C interface, 5-point touch with interrupt support
- Onboard voltage regulator, supports 7~36V wide range power supply
- Onboard RTC chip and rechargeable battery to ensure time data is not lost when power loss
- Onboard CAN, RS485, I2C interface, TF card slot, MX1.25 2P battery header, and digital isolated IO interfaces, etc.
- Supports passive and active digital input, with bi-directional optocoupler isolation
- Supports digital output with optocoupler isolation, provides higher driving capability with up to 450mA sinking current
- Onboard LED indicators for indicating the power and battery recharging status
- Supports flexible clock, module power supply independent setting and other controls to realize low power consumption in different scenarios
Excellent display performance, 160° wide viewing angle
supports touch function with I2C interface, 5-point touch for flexible operation and smooth multi-point UI interaction
Supports the expansion of multiple peripherals via CAN, RS485, I2C and isolated IO interfaces
Comes with two types of screw terminals, allowing for bottom or back wiring, which is more convenient to integrate into various application scenarios such as DIN rail or embedded devices
