The M10 hash board contains 35 chips in series, with 3 chips in each group. Chip model: 1800, 105 chips on the whole board
Each set of voltage is provided by independent LDO 1.8V and 0.9V voltage
The M10 hash board has a 24M clock crystal, a temperature sensor and an eeprom to form the signal group of the entire hash board.
Signal direction: CLK-RXD-RST is transferred from U1 chip to U105, TXD is reversed from U105 to U1
The test point is: RST-CTS-RXD-TXD-CLK.
A = test point location
B = test point name
Normal parameters measured:
CLK = 1.8V
RXT = 1.8V
TXD = 1.8V
RST = pull up 1.8V, pull down 0V
