2.4 GHz RF module with nRF24L01+ chip. The module has an RP-SMA connector with reverse polarity, allowing the connection of an external antenna. The system has a built-in 3.3 V stabilizer and IO lines with a tolerance of 5 V. SparkFun WRL-00705

The Step Down DC-DC converter module (MP2307) allows to obtain 0.93..18V output voltage at 4.75..24V input voltage. The output voltage is regulated by a potentiometer

LED RGB WS2812B, Black Strip, 5m, 30LEDs / m, no waterproof

Three-axis accelerometer module with MMA8452 system; I2C bus

This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its dual robust VNH5019 motor drivers operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per motor, or a continuous 24 A (60 A peak) to a single motor connected to both channels. Pololu 2507

Ultra-low-power 32-bit MCU ARM®-based Cortex®-M3 with 512KB Flash, 80KB SRAM, 16KB EEPROM, LCD, USB, ADC, DAC, LQFP64, STM, RoHS

Design a clock, timer or counter into your next project using our pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments, there are decimal points on each digit and an extra wire for colon-dots in the center (good for time-based projects). Adafruit 813

The ultrasonic distance sensor modUS-015 is based on the analysis of the delay of reflection of the ultrasonic wave from the obstacle - the range of the sensor from 2 to 400 cm with an accuracy of 0.3 cm + 1%

Compact GPS Module Ultra Low Consumption, RoHS

TFT display module 3.2 with touchpanel and SD card slot, 40-pin
