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 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.

A ESP32 NodeMcu WiFi CP2102 Module with Built-in Antenna, MicroUSB Connector, Bluetooth BLE 4.2, Analog Digital Converter, GPIO with PWM Functions, 12C, SPI, Etc and Supports Remote Firmware Upgrade.

A Module with GPRS Antenna, operation Wireless and SIM Card.

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 Module is a Rotary Incremental Encoder. It encodes the shaft rotation signal and outputs the signal by electronic pulse. The Grove –Encoder is a module of the Grove series and has a standard Grove interface. When you need to add a knob to your project, for example a volume knob for a speaker, a selection panel or a digital input, this should be your first choice.

The Rotary Encoders are similar to Potentiometers, however, as they have no physical limits, they can run indefinitely. However, the similarity to a potentiometer is only physical, instead of having a variable resistance, in this type of Encoder we have an impulse output with 20 impulses per turn. In addition to the impulse output, it also has a push button function with two dedicated pins that close when we press the Encoder shaft.

The Sensor of Image Charmed Labs Pixy 2 CMUcam5 is smaller, faster and more capable than the original Pixy. Like its predecessor, Pixy2 can learn to detect objects, just by pressing a button. In addition, Pixy2 has new algorithms that detect and track lines for use with line following robots. The new algorithms can also detect intersections and "traffic signs". Traffic signs can tell your robot what to do, such as turning left, turning right, slowing down, etc.
