The Hanqiang HQ3580-H01 power supply has a maximum load of 3500W and a conversion efficiency of more than 94%. It can adapt to the complex power supply requirements of the mining farm (AC input 176V~300V), with IIC software communication, high reliability, good performance, and comes with a 16A power cord.

The mining machine power supply and the hashing board are connected by two whole pieces of gold copper plates. The control board is powered by a 6-pin power cable. The function of the power jumper is to start the machine without software. There is a saying: With a gold medal in hand, mining is not a problem. With a pineapple in hand, I have Gu Ling.

Control Board The ipollo Pineapple G1 Grin miner uses a control board model: AWH3. The panel interface is defined as: Ethernet interface, TF card slot, IP report button, reset button and status indicator light.

The ipollo Pineapple G1 Grin mining machine has three built-in hashboards, which are installed into the casing through the slots designed in the casing.

There are 10 independent heat sinks on each computing board. Rubber pads are installed on the back of the computing board to prevent bumps. Rubber pads are also installed separately on the heat sink close to the side of the casing to achieve all-round protection.

Continuing to explore, we found that under each independent heat sink is a separate computing board, and the independent computing board carries an independent chip. The thermal pad used between the chip and the heat sink conducts the heat of the chip to the heat sink.

The ipollo G1 Grin miner is equipped with 30 G22 12nm FinFET process ASIC chips. It is understood that this Grin chip has a built-in efficient Cuckatoo cycle computing core, with a chip area of ​​38x38mm. It is the world's first dedicated chip that supports Grin, and it is also the largest single chip in the ASIC mining machine on the market.

Fan ipollo Pineapple G1 Grin mine uses 4 1438B DC12V 5A cooling fans to provide heat dissipation for the mining machine.

The casing of the ipollo Pineapple G1 Grin mining machine uses an aluminum alloy one-piece molding process, with reserved slots for the computing power board and holes for threading.

ipollo G1 Grin mining machine mining configuration ipollo G1 Grin mining machine defaults to DHCP to automatically obtain the IP address. You can find the IP address of the G1 mining machine through the local router or with the IP report button, and enter the IP address into the browser address bar to enter the mining machine login page. The default login username and password are both admin.

The home page displays the mining machine operation status interface, which mainly displays the current computing power, fan speed, temperature, mining pool rejection rate and other parameters of the ipollo pineapple G1 mining machine.

In addition to the miner status, there are three menu sections on the left side of the control panel page: system operation status, system configuration and network configuration. The commonly used configurations are mainly: mining pool/miner configuration; network configuration; check chip status; modify login password; update firmware.

Select the menu miners (mining machine status) / Pool Configuration (mining pool configuration) page to configure the mining pool and miners.

Select the menu miners (miner status) / Network Configuration (network configuration) page to choose to set the miner to DHCP (automatically obtain IP address) or Static (static IP address).

In the menu miners (miner status) / Asia Status (chip status) page, you can view the operation status of each chip. When it is operating normally, the chip position is green and the value is displayed normally. When the chip fails and does not work, the chip position is gray and no value is displayed.

ipollo Pineapple G1 Grin Miner Test Data
After the Caiyun team tested the ipollo Pineapple G1 Grin mining machine for more than 24 hours, the mining machine started mining immediately after it was turned on and set up, and it ran smoothly during the period.
The only shortcoming is that the power consumption of the ipollo G1 Grin mining machine has been fluctuating between 2000-3000W during operation , and the power consumption of the mining machine cannot be defined. Later, the ipollo Technology engineer confirmed that the mining machine has been tested for a long time and the power consumption is determined to be 2800W. The power consumption in the picture is captured for reference only. The fluctuation of power consumption can explain why a mining machine with a power consumption of 2800W needs to be equipped with a 3500W power supply.

When the air inlet temperature is 32 degrees, the air outlet temperature of the mining machine is 46.4 degrees, and the temperature difference is 14.4 degrees, which is within the normal range. The air outlet temperature of the power supply is 38.1 degrees, and the temperature difference is 6.1 degrees.
The fish pool shows that the average computing power of the ipollo Pineapple G1 Grin mining machine in 24 hours is 40G/s. Combined with the power consumption of 2800W, the power consumption ratio of the Pineapple G1 Grin mining machine is calculated to be 70W/G.

According to the daily theoretical income calculation of the fish pool, the daily output of the ipollo pineapple G1 Grin mining machine with 40G computing power is 363 Grin, and the theoretical income is 1,022 yuan. The mining income has exceeded the 1,000 yuan mark, ranking first in the POW mining income ranking.
