We've had quite a few requests to share final schematics. Let's start with H series.
Screen test video that was requested by one of our backers. Beta prototype of the M1.
Initial stages of the enclosure design process.
We’re so thankful to the community. Our kickstarter campaign is off to a great start, and we couldn’t have done it without your support.
When it came to infrared, we had a few basic criteria:
So, we looked at the Vishay IR Receiver Modules. Specifically the tsop753 and its sensitivity around the 38kHz band-pass center frequency. This was necessary to guarantee that our device's IR transmitter is in harmony with the TSOP753's reception capabilities. A cool thing about the TSOP753 is its improved immunity against ambient light. It also has a low profile of 2.35mm, which helps with a compact device like ours. It’s reliable and widely available. If it ain’t broke, don’t fix it.
Working with IR receivers and components, here's what we further considered:
Crucial to devices such as ours is the Sub-1 GHz transceiver. We definitely wanted to employ a transceiver that is capable throughout a wide range of frequencies. (Refer to Frequency Range in chart below). The Si4463 transceiver boasts optimal sensitivity, allowing it to discern even very faint signals. Additionally, its robust power output ensures extended range communication capabilities. And it’s nice to have data rates up to 1 megabyte per second as opposed to only 500 kilobytes per second.
We liked the Bluetooth capabilities of the STM32WB, but were underwhelmed by its overall performance. Besides, Bluetooth was already integrated in our wireless components. In the end, the H series of MCUs from STM microcontrollers was the only way to fly.
Beyond sheer performance, we chose the STM32H5 series over the STM32WB series for its enhanced security features. The STM32H5 offers a robust suite of security capabilities including hardware side security. Moreover, the STM32H5's ability to securely store cryptographic keys was something we hoped we could integrate, especially when considering applications like Two-Factor Authentication (2FA), where the integrity and confidentiality of stored keys are paramount.

Breakout modules for the M1 will utilize GPIO, enabling versatile interfacing with various electronic components.
Hi, I missed the Campaign order date as I had a lot going on at the time, and it slipped my mind. Is there a way I can still order the M1? Will I have to wait until they start shipping before they are available to order? Thanks.
We will certainly look into incorporating multilingual support into our firmware.
can your device intercept and copy a rolling code or prevent any NFC or RF ID stealing if it is in your pocket either jaming it or cancelling any thoughts on it ??
The M1 is not intended for circumvention of security features in other devices such as rolling codes. Signals can be captured for analysis.
After we have fulfilled all rewards from our Kickstarter campaign, the M1 will be available for purchase on our website.
Is some type of small speaker or buzzer planned to provide feedback on the buttons for example and navigation between menus and functions?
Yes, we will include a buzzer/speaker and indicator LED in the final version of the M1.
POCSAG capabilities?
What protocols of the frequency range will be available for RX/TX? AM, FM, NFM, WFM, Digital? Radio Scanner opportunity?
Thanks in advance
The M1 supports several types of digital modulation, including 2-FSK, 4-FSK, GFSK, MSK, as well as OOK and flexible ASK shaping.
Hey I just found this project today, I was trying to backed but seems like now is close your kickstarter, there is still a way that can i have early access to get one?
can we connect it with laptop from a remote access and then operate the M1? any support for these process?
As US,Canada,brazil etc and even easy buy is banned for eg: amazon will you be selling them on physical and your exclusive website ?
The M1 itself does not natively support direct remote access over the internet due to its design philosophy and security considerations. It is primarily designed for physical interaction. However, there are indirect methods to achieve remote interaction:
Serial Connection Over USB: You can connect the M1 to a computer via USB and use it through a serial connection. This allows you to send commands and receive responses from the M1 using its command-line interface (CLI).
Custom Scripts and Automation: By writing custom scripts that run on your computer, you can automate certain tasks with the M1. These scripts can be triggered remotely if your computer is accessible over the internet (e.g., via SSH).
We will sell them directly on our website.
Regarding Amazon, we hope to offer our products on their platform (not confirmed).
Please add more memory, meybe fit small usb flash or other?
Many people dreaming about old BBS or PocketRadio. Gopher , IRC or similar old way communications.
Yes, we will employ MicroSD card (up to 256gb) for expandable memory
I can send emergency message using mesh network ?
Is possible add removable antena for different band?
Sending Emergency Messages via Mesh Network with M1: Not supported natively. M1 does not have built-in mesh networking capabilities for emergency messaging.
Adding a Removable Antenna for Different Bands to M1: Not possible without significant modifications. M1 is designed with fixed antennas for its supported frequencies

In this forum, or a post, thy will be done... Someone will severe them aerial traces and solder a resister and have some I and Q, Rx Tx inputs outputs modded.
I'm a backer but I'm awaiting developments but what breakout modules are you thinking... They just GPIO or proprietary?
