WIFI Kit series is the new development of the cost-effective networking program, the main chip using Lexin ESP32, Tensilica LX6 dual-core processor, clocked at 240MHz, computing power up to 600DMIPS, chip built-in 520 KB SRAM, 802.11 b / g / N HT40 Wi-Fi transceiver, baseband, protocol stack and LWIP, integrated dual-mode Bluetooth (traditional Bluetooth and BLE low power Bluetooth).
This product is based on the WIFI Kit 32 added SX1278 chip, that is,for LoRa remote modem, 433MHz frequency, about -148dBm high sensitivity, +20 dBm power output, high reliability, transmission distance (measured open area communication distance 2.6Km).
Onboard 32MByte Flash, Wi-Fi antenna, 0.96-inch blue OLED display, lithium battery charging circuit and interface, CP2102 USB to serial chip, the perfect support for Arduino development environment, can be very simple and fast for program verification and product development.
Note: This item come unassembled, soldering is required, not equipped with lithium battery.
