Introduction

Grin was born in November 2016. It is a hidden encrypted digital currency (anonymous currency) developed based on the Mimblewimble privacy protection protocol. The main network of Grin was officially launched on January 16, 2019. Using the Cuckatoo32 Pow (cuckoo) encryption algorithm, the Grin mining algorithm Cuckatoo has 2 modes c29 (graphics card mining machine) and c32 (Asia mining machine). After the mainnet launch of Grin in 2019, it became the Internet celebrity coin of the year. At that time, many teams in the industry tried to develop the Grin ASIC mining machine, and the launch time node was concentrated in the summer of 2019. It is a pity that the thunder was heavy and the rain was small. Abandoned development. On August 22 this year, at the "2020 Global Blockchain Computing Conference" held in Chengdu, Sichuan, Zhejiang Love Pineapple Technology Co., Ltd. displayed the world's first Grin professional ASIC mining machine ipollo Pineapple G1, ipollo The first public appearance of the Pineapple G1 caused a stir in the industry. According to reports, the Grin ASIC mining machine ipollo G1 has three characteristics: the highest mining revenue, the lowest electricity cost ratio, and the highest technical content. The daily mining output Grin revenue has exceeded the thousand yuan mark. Now there is an ipollo Pineapple G1 Grin ASIC mining machine in front of the editor, it's time to feel the temptation of mining one thousand yuan a day.... Appearance of ipollo Pineapple G1 Grin Miner ipollo Pineapple G1 is packed in an industrial carton with a logo of Love Pineapple Technology on the side, the physical size is: 535x450x307mm, the logistics weight is 21.8KG, and the interior is protected by two pieces of pearl foam.

The ipollo Pineapple G1 Grin mining machine is designed as a two-cylinder all-in-one machine. The physical size of the mining machine is manually measured by Xiaobian: 450x202x350, and the weight of the whole machine is 20.1KG. The ipollo G1 Grin mining machine integrates the power supply and the mining machine into one. One side is the power supply, and the other side is pasted with the Logo of Love Pineapple Technology, the brief description of the mining machine and the precautions for use. The cooling system of the ipollo G1 Grin mining machine uses 2 air supply, 2 exhaust air and a total of 4 fans. The mining machine can be placed upright or flat, which is convenient and flexible. ipollo Pineapple G1 Grin Mining Machine Component Analysis The ipollo Pineapple G1 Grin mining machine consists of a chassis, power supply, computing power board, control board and cooling system. After opening the shell, you can see the connecting wires of the various components of the mining machine. The cooling fan is powered and controlled by the control board, and a protective rubber ring is installed at the contact position between the fan and the chassis. The design is thoughtful and careful from the observation of small details. Power ipollo Pineapple G1 Grin mining machine is equipped with a Hanqiang HQ3580-H01 power supply. Hanqiang HQ3580-H01 power supply has a maximum load of 3500W and a conversion efficiency of up to 94% or more. It can adapt to the complex power supply of the mine (AC input 176V~300V ) requirements, with IIC software communication, high reliability, good performance, with a random 16A power cord. The power supply of the mining machine and the computing power board are connected by two whole pieces of golden bronze medals. The power supply of the control board uses a 6pin power cord. The function of the power jumper is that it can be turned on without software. There is a saying that goes well: gold medal in hand, no worries about mining, pineapple in hand, I have ancient spirit. Control board The ipollo G1 Grin mining machine uses a control board with the model name: AWH3, and the panel interface is defined as: Ethernet interface, TF card slot, report IP button, reset button and status indicator. Hashboard ipollo Pineapple G1 Grin mining machine has three built-in hashboards, which are installed into the casing through the card slot designed by the casing. There are 10 independent heat sinks distributed on each hash board, and a rubber pad is installed on the back of the hash board to prevent bumping. Continuing to explore, it is found that under each independent heat sink is a separate computing power board. The independent computing power 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 Pineapple G1 Grin mining machine is equipped with 30 12nm FinFET process ASIC chips of model G22. It is understood that this Grin chip has a built-in high-efficiency Cuckatoo cycle computing core. The chip area is 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 The ipollo G1 Grin mine uses 4 1438B DC12V 5A cooling fans to provide cooling protection for the mining machine. Chassis The chassis of the ipollo G1 Grin mining machine is made of aluminum alloy one-piece molding process, and the card slot and threading hole of the computing power board are reserved. ipollo Pineapple G1 Grin mining machine decomposition full picture , enter the IP address into the browser address bar to enter the miner login page. The default login username and password are both admin. The homepage shows the mining machine operation interface, which mainly displays the current computing power, fan speed, temperature and mining pool rejection rate of the ipollo G1 mining machine. In addition to the miner status, there are three menu sections on the left side of the control panel page: system running status, system configuration and network configuration. Several commonly used configurations are: mining pool/miner configuration; network configuration; viewing chip status; modifying login password; updating firmware. Select the menu miners (miner status)/Pool Configuration (mining pool configuration) page to configure mining pools and miners.
