Versatile Wireless Multitool: Open Source Sub-GHz, NFC, and IR Capabilities

MostaTek, a cutting-edge technology company based in California, is making waves in the industry with its latest innovation - a multitool that has the capability to access a wide range of NFC, sub-GHz RF, and infrared systems. This groundbreaking device, known as the M1 RF multitool, is currently in development by MostaTek and is set to revolutionize the way we interact with various technologies.

The M1 RF multitool is powered by the STM32H5 series ARM Cortex M33 microcontroller from STMicroelectronics and features a 1.54-inch LED screen along with a 2100mAh battery that allows for up to 14 days of continuous operation. MostaTek has announced plans to launch a GitHub repository for the system in August, providing developers with the opportunity to explore and customize the device to suit their specific needs. Additionally, the company will offer pre-made software plug-ins to enhance the functionality of the M1.

One of the standout features of the M1 multitool is its ability to detect, record, and emulate RFID cards and fobs, including smart locks and animal microchip tags. Equipped with a specialized 125 kHz antenna for common access system protocols like EM-4100 and HID Prox cards, as well as 13.56 MHz compatibility for a wide range of NFC tags, the M1 ensures precise and reliable readings every time. The device is built around the Si4463 wireless transceiver, offering broad frequency coverage from 142 MHz to 1050 MHz and integrated signal analysis tools for in-depth exploration of radio systems.

Moreover, the STM32H microcontroller incorporates TrustZone hardware to safeguard sensitive data such as access codes and personal information, providing users with peace of mind regarding data security. With a microSD card slot supporting up to 256 gigabytes of storage, the M1 offers ample space for storing essential information and data. Additionally, the device utilizes an Espresif ESP-32 C6 dual-core RISC-V system on chip for WiFi and Bluetooth connectivity, ensuring seamless communication with other devices.

Featuring an infrared sensor for controlling a wide range of devices including TVs, stereos, and air conditioners, the M1 comes equipped with a library of common commands for functions such as adjusting volume and powering appliances on and off. Its IR Learning function allows the device to learn and replicate signals from existing IR remotes, providing users with a convenient and versatile control solution. With 12 GPIO pins capable of handling 5V for various hardware interactions, the M1 offers extensive customization options for button functions and information display.

Developers can look forward to Arduino and PlatformIO compatibility upon the M1's release, with the potential for additional updates and features post-release to further enhance its functionality. Currently available for crowdfunding on Indiegogo, the M1 is expected to ship in September 2024, offering tech enthusiasts and hackers a powerful and versatile tool for exploring and interacting with a wide range of technologies.
