The HC-12 433MHz Transceiver is a wireless communication Module, which is based on the RF SI4463 chip, has a built-in microcontroller and can be configured by AT commands, the maximum output power is 100mW (20dBm) and the receiver sensitivity differs from: 117dBm to -100dBm, depending on the transmission speed. Accepts 3.2V - 5.5V and can be used with 3.3V and 5V UART voltage devices.

This board is the combination of 3 extremely interesting products: a ESP32 Module with WiFi and Bluetooth, a oLED Display and a battery charging and charging system Lithium-Ion 18650.

The ESP32-CAM is a WIFI + Bluetooth Development Card based on the ESP32 Chip, with the additional possibility of using a camera. It is ideal for a variety of loT applications.

This ESP8285 ESP M2 Module provides easy-to-use WiFi for any UART port and is compatible with the HC-06 Bluetooth modules. If your project uses Bluetooth, it is very easy to convert it to WiFi. Using the integrated web interface, WIFI-UART communication can be configured for TCP or UDP sockets on any port.

Solid State Relay - 8 Channels

The motor shield is based on the L298 , it is a double complete bridge driver designed to drive inductive loads, such as relays, solenoids, DC and stepper motors.
