Product introduction
High Light
More Powerful MCU
The ESP32-S3R2 offers 2MB of PSRAM and is equipped with an external 16MB Flash, making the upgraded memory configuration more suitable for Ul and complex system design.
Higher Transmission Power
The device is available in high-power and low-power versions. The high-power version offers a transmit power of up to 27±1dBm, enabling longer communication distances and adaptability to a wider range of application scenarios..
More Peripheral Interfaces
•Added SH1.25*2 solar panel interface, supports 4.7~6V solar input.
•Added SH1.25*8Pin GNSS interface, GNSS power can be individually controlled.
•SH1.25*2 lithium battery interface
Compatible with V3 Pinout
Almost entirely retains the form factor and pin layout of V3, while adding additional pins. The pin plating process has been upgraded from silver plating to gold plating.
