FAQ: Basics
What is my Braiins OS version?
You can find the current installed firmware version in the footer section of all the pages.
Can I mine on any pool with Braiins OS firmware?
Yes, you can mine on any pools which have asicboost supported with Braiins OS firmware.
However, if you mine on Braiins Pool you will get a 100% discount on pool fee.
Same two miners, but both showing two different 'default' Voltages
That is normal. Each miner is different, chips are different.
CGMiner GPL-compliance vs. BOSminer
CGMiner was originally a fully open-source software available under a General Public License (GPL) which requires anybody who modifies the code to publish their sources publicly. However, hardware manufacturers have ignored the GPL and typically do not publish their CGMiner forks in a timely manner if at all. Many other firmwares also rely on CGMiner but do not publish their sources.
We feature-matched CGMiner in our own mining software, BOSminer, which we wrote from scratch in Rust language. This means that Braiins OS is not in violation of any GPL because it is based on BOSminer rather than CGMiner.
What SD card should I use?
Use the MicroSD card with a maximum capacity of 16GB. Recommended is to have less than 16GB. Larger capacity MicroSD cards are not recommended, because you can face issues with the firmware.
Can I remove a hashboard and still run the other 2 while I repair the first one?
Yes, but remove the hash board while the miner is turned off.
If I have an internet outage does this firmware turn off the hashboards?
It will stop and try to resume the connections.
The longer it takes to connect, the longer the retries take until about 1 hour (i.e. after an 1 hour outage, it can take 1 hour before the next attempt to connect).
Due to the use of DNS cache (dnsmasq) DNS issues can also make it take longer, it is important to add more pool URLs (same pool with different port doesn't help).
How can I keep my miners hashing during an internet outage or pool disconnection?
Setup the "drain" pool that allows miners to continue hashing even when all pool connections are lost.
This is primarily used by operators in cold climates to prevent hardware from cooling down rapidly during connectivity issues, reducing the risk of thermal stress or hardware failure when service is restored.
To enable it, navigate to Configuration > Pools and add a new pool at the bottom of your priority list with the following URL: drain://localhost and username: drain.
Note: While in "drain" mode, your miners will continue to consume electricity and generate heat, but the hashrate is effectively sent to a void and will not generate any revenue.
When I go to my miners address, it still shows the Bitmain firmware.
You need to clear the browser cache or try a different browser.
I checked the power at the wall and power reported on Dashboard and it seems, there's a difference between them.
Yes, the data on the Dashboard is an estimation and may not be accurate, measure yourself at the wall.
