If youd like to join the discord where Skot and many other developers with the same ideas in mind are, look no further! We have built a small community for Open Source mining. Skot and myself are the co-owners of this server. come see what all we have to offer!
Keep in mind, this server has been transferred from V1 which the owner went missing due to health complications. This means not all the original messages are available. if you join and would like to see the original server please contact myself, or the moderation team!

We hope to see you there!

About JaBIT Solo Miner

- Is the first fully open source hardware Bitcoin ASIC miner
- Powerful bitcoin miner in small factor( just slightly larger than size of a credit card), can mine any SHA256 Coins such as BitCoin(BTC), Bitcoin Cash(BCH) , Bitcoin SV (BSV), Litecoin Cash (LCC), NameCoin, Digitbyte, etc
-Uses efficient BM1397 Asic chip for mining. It is unlocked for overclocking (Voids warranty). It features a single 7nm technology BM1397 chip.
- Stock hashing speed: 200 GH (please note: these miners run very hot and require active cooling such as fan). It comes equipped with high RPM fan.
- High Speed: 350 GH++ (Running at clock speed of 545 MHz Higher speed requires above spec). To reach max speed of 500GH you will need 3 Amps per miner or PSU to supply 3A per miner!.  JaBIT comes with PSU to supply 5V, upto a Max 6A. i.e Max 30W for each miner.
- Completely silent operation, includes Mini heatsink to cool miner.
- Compatible with Windows, Mac and Linux OS using cgminer software. Includes an Online user manual with instructions for easy setup.
- Mining Algorithm: SHA-256, Minable Coins: Bitcoin (BTC), BitcoinCash (BCH), Acoin (ACOIN), Curecoin (CURE), Joulecoin (XJO), Unbreakable (UNB), Peercoin (PPC), Mark (DEM), Terracoin (TRC), BitcoinSV (BSV)


Advantages:

- Standalone: can mine directly to your pool over WiFi. No External computer needed.
- Embedded: low cost, low maintenance, high availability, high reliability, low power.
- ASIC: based on the very efficient BM1397 from Bitmain.
- Versatile: solo/pool mining, autotune power/heat/efficiency.
- Open Source: All design files are available .


Features

- ESP32-S3-WROOM-1 wifi microcontroller on board
- TI TPS40305 buck regulator steps down the 5V input to power the BM1397
- Maxim DS4432U+ current DAC digitally adjusts the BM1397 core voltage from 0.04V to 2.4V
- TI INA260 power meter measures the input voltage and current of the miner
- Microchip EMC2101 measures the BM1397 internal diode temperature. Also PWM controls the fan and monitors tach output.
- Two sweet RGB status LEDs


Current Status:
- The hardware has been built and tested. Current Batch is shipping now.
- Using cgminer on a separate computer, the JaBIT Solo Miner (Bitaxe v2.2) can mine in excess of 400 GH/s

Amazing work, guys! I've got a lot of catching up to do. I definitely need to buy or build myself one to check it out hands-on style.
I definitely love the feature-set. You achieved standalone operation with fully digital core voltage and fan control; that's super unique and makes it stand out from the competition. Surely, this should aid in developing larger, multi-chip variants, as well! How about creating a dedicated thread for it here on Bitcointalk now? Wink

One thing that is unclear to me from the online shop listings is whether it comes with the case and power supply or not.

Seeing home power enthusiasts gradually achieve the world's highest chip minimum wattage is a milestone, but seeing resellers now selling it for hundreds of dollars more than older equipment still feels like a high barrier to entry for beginners, not to mention extra shipping from around the world

 Huh

Anyone here knows where to get the 3D printed case STL file?

I just discovered this thread.
I have been following the project over Telegram.
I opened a thread about Nerdminers, which you all already probably know, and referenced Bite as a (quasi) totally open-source project ASIC miner.
I am cross-referencing the thread for our fellow forum users who might be interested.

Have a look here:
