3S 20A Li-ion 18650 BMS Lithium Battery Protection Board is a Battery Management System (BMS) designed for 3-cell 18650 Li-ion battery packs. It offers overcharge, over-discharge, short-circuit, and overcurrent protection to ensure the safe operation and longevity of your battery packs.
1.3-inch OLED display module with a 128×64 pixel resolution and a blue monochrome screen. It uses an I2C/IIC interface for communication, requires a 4-pin connection, and is compatible with 3.3V to 5V microcontrollers like the Arduino. Key features include high brightness, self-emission (no backlight needed), high contrast, low power consumption, and a wide viewing angle
5621BS Red LED Display 2 Digit 7 Segment Common Anode Digital Display 18 Pin 0.56 inch
Transceiver module based on an NRF24L01 allowing a 2.4 GHz wireless connection. This module communicates with an Arduino or compatible microcontroller via the SPI bus.
This is 125K RFID Tag. The RFID technology is used for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications.
Operating on a frequency of 125kHz, these tokens are all pre-programmed with unique ID numbers to communicate wirelessly with RFID Readers over distances of around 10cm or less. This means you can attach it to vehicles or items, keyrings or even pets’ collars to keep track of the location via an array of readers in the office, warehouse or home.
A 5v relay is an automatic switch that is commonly used in an automatic control circuit and to control a high-current using a low-current signal. The input voltage of the relay signal ranges from 0 to 5V.
The HW-201 IR infrared obstacle detection module can detect obstacles within a distance range of 2 cm to 30 cm, with a detection angle of 35 degrees.
It can operate with a supply voltage of 3.3 V to 5 V and has a maximum current consumption of 100 mA. The module outputs a digital signal, high when an obstacle is detected, low when no obstacle is detected.
The infrared LED has a wavelength of 940 nm and an operating frequency of 38 kHz. The module operates at temperatures between -25 °C and +55 °C.
