The VMA214/RFM69HC Transceiver Module operates over a wide frequency range, including license exempt ISM (Industry Scientific and Medical) frequency bands 315, 433, 868 and 915MHz. All major RF communication parameters are programmable and most can be configured dynamically.

TOSR02-T - USB / Wireless 5V 2-channel Relay Module Support for temperature sensor

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

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

The W5500 Ethernet Shield v1.0 can be used to provide your projects with internet connectivity.W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY embedded. The shield also have two Grove connectors and a microSD card socket to support projects which require storing large amounts of data from Grove sensor. The RJ45 port (Where the Ethernet cable is connected to) is low enough to allow you to stack more shields on top of this one if needed.

Finger is a fingerprint sensor that makes fingerprint verification super simple.

The Uart protocol, compact size and ultra low power consumption make the use of MSStack series products very attractive. It performs fast fingerprint matching with the highest level of security and the ideal convenience of the user. You can program to set the level of comparison of the fingerprint recognition and the different security level. If you've ever thought about protecting your project with biometrics, don't forget to include this MSunit Finger.

This unit communicates with the M5Core by UART protocol connected via PORTC.

Can be used to monitor the heart rate of the patient and athlete. The result can be displayed on a screen via the serial port and can be saved for analysis.
