Hey Miners! We're excited to announce the latest FPGA mining board by HashAltcoin, the Blackminer F1 Mini+!

Introduction

Just a few weeks ago, HashAltcoin launched a new FPGA mining board called Blackminer F1 Mini+. Previously, their successful Blackminer F1 Mini became one of the best sellers for those who want to try FPGA mining. Now, they launched another low priced FPGA mining board priced at $189. This board's hashrate are claimed to be around 1.5 times more than the hashrate of F1 Mini, plus it also comes with a cooler. Based on these facts, is F1 Mini+ a better deal than F1 Mini?

Mining and Profitability

As of November 8th 2019, Blackminer F1 Mini+ only supports three algorithms. Here are the available algorithms for F1 Mini+ from HashAltcoin:

Algorithm Coins Hashrate Power
Verus2 VRSC 37 MH/s 110-120 W
Vblake VBK 1.38 GH/s 110-120 W
odocrypt DGB 520 MH/s 110-120 W

Cheers to HashAltcoin for sending us a unit to test. Without further ado, here's our test result:

Veriblock Digibyte (odo) Verus
Frequency 464 MHz 530 MHz 514 MHz
Hashrate 1.37 GH/s 520 MH/s 34 MH/s
Power* 65 W 101 W 30 W
Temperature 44oC 48oC 37oC
Revenue $0.82/day** $0.43/day** $0.44/day**

* Power on the wall (minus PSU's idle state power)
** Data per Nov 7, 2019

Not only is the hashrate very close to the advertised number; even the power consumption is lower than expected!

That means more profit compared to F1 Mini because the electricity cost is lower than expected (expected: 110-120W).

If you are interested, you can read more details on our test results here.

The mining process is extremely user friendly –  easily plug and play. However, for odocrypt, currently, it only supports the default mining pool URL.

Pros

  • 📈 Higher Hashrate Compared to F1 Mini. This means F1 Mini+ can generate more coins.
  • 🤑 Cheap. Priced at $189/unit (includes heatsink and fan!). It's one of the most affordable FPGA in the market. Low entrance price to FPGA mining.
  • 👨‍💻 Team of Bitstream Developers. They have their team of developers continually looking for coins worth mining. Currently, HashAltCoin has the most public bitstreams available, over any other board.
  • ✅ Easy to Use. You only need a PSU and an ethernet cable. Just access your F1 Mini+ IP address and set it all up from there.
  • ⚡️ Low Power Consumption. It only draws 120 Watts max.
  • 👂🏻 Meant for Silent Operation. The heatsink and fan cool down the chip in silence.

Cons

  • 3️⃣ Fewer Algorithm Options. Currently, F1 Mini+ only has three available bitstreams.
  • ⛔ No SDK or community support.  F1 Mini+ is a closed platform, and only HashAltcoin can make bitstreams for these boards.
