In 2023, is it suitable to use miners to mine or buy coins? In recent years, with the increasing popularity of blockchain technology and the rapid development of digital currency, more and more people have joined the team of mining and buying of coins. In 2023, for most people, choosing to use a miner to mine or buy coins will be a critical decision. Advantages and disadvantages of miners High power consumption, high cost, and high technical requirements are the salient features of miners' mining. But at the same time, miners also have a stable income from mining and have the advantage of controlling the speed of block verification. Here are a few viable Bitcoin miners and their profitability in 2023. Antminer S19 Pro is a miner produced by Bitmain , which is very popular in the market. It is equipped with 114 BM1398 ASIC chips , which can achieve a faster and more stable mining experience. It is estimated that the average daily income of this type of miner in 2023 will exceed 120

Chip name: M24C02-DRMF3TG/K
Chip location: UP37
Chip silkscreen: 24C02RP
M24C02-DRMF3TG/K is a serial memory (EEPROM) with 2KBIT memory size, I2C memory interface, operating power supply voltage between 1.8V ~ 5.5V, and operating temperature between -40°C ~ 125°C. Chip data retention time, up to 1 million write cycles, Schmitt trigger input for noise filtering.
Chip name: SN74LVC1T45DCKR
Chip location: UP39
Chip silkscreen: TAR
Designed for asynchronous communication between two data buses, the SN74LVC1T45 is packaged in SC70(6) technology and is a single-bit non-inverting bus transceiver. The fully configurable dual rail design allows each port to operate over the full 1.65V to 5.5V supply work within the scope.
Chip name: SGM3750
Chip location: UP38
Chip silkscreen: 75018093
With an integrated switching FET rated for 40V, the SGM3750 is a boost converter that can drive LEDs in series. It is marked in a green TDFN-2×2-6L package, and the operating ambient temperature is between -40°C and +85°C. The boost converter operates at a fixed switching frequency of 650kHz to reduce output ripple, improve conversion efficiency, and allow the use of small external components that prevent the output voltage from exceeding the IC's absolute maximum voltage rating under open LED conditions.
Chip name: CT75MMR
Chip location: UP36
Chip silkscreen: 75825J3A
The CT75 is a digital temperature sensor chip with an accuracy of ±0.5°C and is compatible with SMBus, I2C, and 2-wire interfaces. The operating temperature range is -40°C to 125°C, and the chip has built-in programmable over-temperature/under-temperature protection. In addition, it includes a high-precision bandgap circuit, a 12-bit analog-to-digital converter that provides 0.0625°C resolution, a calibration unit with non-volatile memory, and a digital interface module.
Chip name: Si9183DT-AD-T1
Chip location: UP34
Chip silkscreen: A9jMU
The Si9183DT-AD-T1 is a high-performance and small-size 150mA CMOS LDO (low dropout) regulator. Its ultra-low ground current and dropout voltage extend battery life in portable electronics. The device offers better line/load transient response and ripple rejection than bipolar or Bi CMOS LDO regulators. It is designed to maintain regulation while delivering a 300mA peak current. It is packaged in a thin SOT23-5 and operates between -40°C and 85°C.
Chip name: MMBT3906
Chip silkscreen: 2AB
The MMBT3906 is a 220mV -200mA MOS chip in a SOT-23 package. The operating crystallization temperature is between -55°C and +150°C.
