This kit includes a keyestudioREV4 board, a transparent 400-hole breadboard, a black chassis, 65 pieces of breadboard jumper wires and a blue USB cable. For more detailed use, you can check it as follows.
keyestudio REV4 Board
keyestudio REV4 is a microcontroller board based on the ATmega328, fully compatible with ARDUINO UNO. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, 2 ICSP headers and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
400 Tie-Points Breadboard:
This is a half-size transparent breadboard, good for small projects. It has 2 power rails on both sides, a standard double-strip in the middle with 30 columns and 10 rows - a total of 400 tie in points.
This tiny breadboard also has a self-adhesive on the back, so you can stick it onto an Arduino protoshield or keyestudio chassis. Dimensions: 85*57*10mm
This keyestudio chassis of ABS material is particularly designed for project experiments. It is waterproof and has great stability. You can fix both arduino board and small breadboard onto it.
This brand-new USB extension cable is sealed with PVC shell, flexible and durable. Length: 50cm.
Jumper Wire Pack of 65:
M/M breadboard jumper wire pack, totally 65 pieces in several types of length and many colors. The length of the wire: 12cm, 16cm, 20cm, 24c
