- Comprehensive Connectivity
- The CmRat is equipped with a wide range of ports, including Gigabit Ethernet with Power over Ethernet (PoE), HDMI, USB Type-C, MicroSD slot, and an NVMe hard drive slot. This extensive connectivity makes the CmRat highly versatile and capable of supporting various configurations.
- Security Features
- Security is a priority for DTV Electronics. The CmRat supports login with a password, backups using a seed phrase, and connections through TOR to enhance privacy and security.
- Upgradability
- The CmRat is designed with scalability in mind. Users can upgrade the NVMe storage, compute module, and even the heatsink and fan, ensuring that the device can adapt to future needs. You can install whatever OS you want and upgrade whatever part you need.
DTV Electronics CmRat Bitcoin Node: How It Works?
Setting up the CmRat involves a few steps:
- Mount the Compute Module: The user begins by mounting the chosen compute module onto the CmRat carrier board. This module houses the CPU and RAM, which are essential for running the device.
- Install the Operating System: Once the hardware is assembled, the next step is to install the preferred operating system onto a MicroSD card, which is then inserted into the CmRat.
- Cooling and Power: To ensure optimal performance, particularly during high workloads, users can attach a heatsink and fan to the compute module. The CmRat is powered via the Ethernet port, which simplifies the setup by reducing the number of cables needed.
- Begin Operation: With the hardware and software in place, the device is ready to use.
If you prefer a hassle-free setup, you can opt for the full node configuration rather than the barebones version.
