DollaTek ESP32 Wireless Stick Lora+WIFI+BLE Development board with 0.49 inch OLED display screen SX1276 Module For Arduino 433MHz - 470MHz

• Compact appearance, powerful computing functions, WIFI function, support for Arduino, rich interface and other product features.
• users can program the product through standard library and simple development language, and quickly complete program verification and product development.
• At the same time, it has an OLED display and a lithium battery interface, which can be used for simple management of charging and discharging of lithium batteries, and can be directly used as a development of handheld devices.
• This product does not directly use the more popular WIFI, LoRa and other modules, but directly based on chip-level development, on the one hand to minimize the size.
• The product's main control chip is a 32-bit processor - ESP32 chip. In addition to the WIFI function, it also supports BLE 4.2 and powerful LoRa wireless communication functions, which can be used as a gateway for IoT products or as a driver terminal product (such as sensors, stepper motors, etc.).
