Canaan Technology Launches New Avalon A13 Series Bitcoin Miners

Canaan Technology Launches New Avalon A13 Series Bitcoin Miners According to the latest news, Canaan Technology announced the launch of the new Bitcoin miner Avalon Made A13 series, including Avalon A1346 and Avalon A1366. Canaan Technology said that the new generation of miners uses advanced ASIC technology, and the A13 series will include two different models. Compared with the 90 to 100TH/s hash rate offered by the A12 series, the A13 series has both hash rate, and energy efficiency has been enhanced. Canaan's CEO said the all-new A13 is a milestone in the company's over-computational energy consumption analysis. The model A1346 has a hash rate of 110 TH/s and an energy efficiency of 30J/TH. Model A1366 has a hash rate of 130TH/s and an energy efficiency of 25J/TH. Comparing the energy efficiency ratio of Bitmain's flagship S19 XP of 21.5 J/TH with that of Bitmain's M50S of 0.026j/Gh, the new series of A1346 is "very competitive" in terms of efficiency at

How many types of chips are on the Antminer S17 Pro hash board?

How many types of chips are on the Antminer S17 Pro hash board?

The chip types on the Antminer S17 Pro hash board mainly include ASIC chips, converter chips, voltage regulator chips, memory chips, temperature sensor chips, MOS chips, controller chips, and voltage monitoring chips. What role does it play in it? We together look!

Easily damaged parts of Antminer S17 Pro hash board introduction

1. BM1397AD ASIC chip

A single S17 Pro hash board has 48 BM1397AD chips located under the heat sink on the front of the hash board and connected to the heat sink through thermosetting adhesives. They are mainly responsible for the hash rate calculation of the whole miner. Therefore, if the hash rate of a single chip is low during the operation, it will result in a low hash rate and no hash rate for the entire hash board.

5. Temperature sensor chip

U245: T451 temperature sensor
The S17 Pro hash board has 4 built-in T451 temperature sensorchips, using WSON-8 packaging technology, mainly used to sense the temperature of the hash board. If the temperature sensor chip is damaged, it will cause abnormal temperature readings. Likewise, if the temperature sensor chip temperature is too low, the hash board will not start, or if the temperature is too high, the miner will stop running.
