MakerFocus ESP32 LoRa Development Board WIFI Bluetooth with 0.96inch OLED Display and 2dBi Antenna
ESP32 LoRa Development Board
Description:
WIFI Kit series is the new development cost-effective networking program of our company, 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 SX1276 chip, that is, LoRa trade; remote modem, 868/915MHz frequency, about -139dBm high sensitivity, +20 dBm power output, high reliability, transmission distance (measured open area communication distance 2.8Km).
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.
