Make a small Video Display with this Bicolor 8x8 LED Matrix. At just 1.2" on a side, it's pretty visible, but not enough to not plug into a breadboard! Each grid has two LEDs inside so it can display red, green, yellow, or multiplexed. This Matrix is bright, Beautiful and modern with beautiful diffused square lens for a stunning look. There are 24 pins on the side, 12 on each, with 0.1" spacing so you can easily connect it to a breadboard with a line on each side for wiring above.

The Console Module with Buttons for Micro: Bit is an expansion gamepad based on micro: bit. You just need to connect the micro: bit, and it will turn into a wireless remote control or a wireless gaming console.

Expansion board For Micro:BIT.

JoyC is a Joystick Module designed for the M5StickC. Supports two-handed operation. The main control chip is STM32F030F4, it uses the I2C communication protocol and the M5StickC host for data transmission. The joystick range is from 0 to 200, includes 12 RGB LEDs, and the bottom of the joystick contains 16340 battery holder.

The 8 Environment Sensors Kit, M5Stack Env Kit, includes the 8 Earth, Angle, Pir, Hub, Light, Rgb, Ir and Env Sensors.

The MAX30100 is a complete solution of Pulse Oximetry System and Heart Rate Sensor. The MAX30100 provides a very small solution without sacrificing optical or electrical performance.

Color is a Light to Digital Color Converter with IR Filter. The TCS3472 Device provides a digital red, green, blue (RGB) return and sharp light detection values. An infrared blocking filter, integrated in the chip and located in the color-sensing photodiodes, minimizes the infrared spectral component of the received light and allows color measurements to be made accurately.

This unit communicates with the M5Core through the Grove (I2C) port. The address is 0x29.

The M5Stick-C is an ESP5 powered M5Stack mini. It's a portable, easy-to-use, open source IoT development board.

Hat SPK is an M5StickC compatible Loudspeaker with integrated PAM8303 Amplifier (Single Channel 3W Type D Power Amplifier), with a High PSRR that eliminates noise and RF interference.

This module integrates a Zhongke Weibeidou AT6558 navigation chip and a MAX2659 amplification chip used to amplify the antenna signal. The AT6558 has high performance, supports many types of satellite navigation system, capable of receiving satellite signals on 56 GNSS signal channels from 6 satellite navigation systems, joint location, navigation, weather and more. The module is able to obtain accurate information of global location, fast and precise positioning for any place.

The module can be widely used in vehicle monitoring, car navigation, on-board navigation, notebook navigation, etc. You can connect it to Port C on the M5core via the Grove cable, which is a standard UART interface.

PuppyC is a programmable four-legged robot base compatible with the M5StickC. It contains the STM32F030F4 Microcontroller, four 5G90 micro servos, a battery holder and an independent switch. The PuppyC base needs to be used in conjunction with the M5StickC controller. After programming StickC, it communicates with PuppyC through the I2C protocol to control the steering movement.
