Features:

There are five USB ports in the motherboard,which are Type-A1 + Type-A2 + Micro-B + Type-C + Lightning.

Type-A1 and Type-A2 support QC3.0/ QC2.0/ AFC/FCP/ SCP/PE2.0/ PE1.1/ SFCP/ VOOC fast charging output.

Type-C supports PPS/ PD3.0/ PD2.0/ QC4+/ QC3.0/ QC2.0/ AFC/ FCP/ SCP/ PE2.0/ PE1.1/ SFCP fast charging output.

Support PD3.0/ PD2.0/ AFC/ FCP/ SCP/ PE1.1 fast charging input;

Micro-b supports QC2.0/ AFC/ FCP/ SCP/ PE1.1 fast charging input.

Lightning supports PD fast charging and 5v2.4a slow charging.

When the input matches the fast charging, the default input is 9V, and the input power can reach 21W.

Support filling and discharging at the same time. It supports fast charging input and output in single port operation and 5V input and output in multi port operation.

Support simultaneous external discharge of Type-A1/ Type-A2 / Type-C ports.

Integrated PPS/PD3.0/PD2.0 fast charging protocol, support input and output bidirectional fast charging.PPS output supports 5-5 9V@3A , 5-11V@2A , PD3.0/PD2.0 output support 5V@3A , 9V@2A, 12V@1.5A . The input voltage supports 5V/9V/ 12V.

Integrated QC fast charging protocol, support QC4+/QC4/QC3.0/QC2.0, support class A.QC2.0 supports 5V/9V/ 12V output voltage. QC3.0 supports 5V-12V output voltage, 200mV / step.

Integrated AFC fast charging protocol, output support 5V / 9V/ 12V. The input supports 5V/ 9V voltage.

Integrated FCP fast charging protocol, output support 5V / 9V / 12V. The input supports 5V/9V voltage.

Integrated SCP fast charging protocol, output support 5V@4.5A.Input support 5 5V 3A.

Integrated with PE2.0 and PE1.1 fast charging protocol, PE2.0 supports 5V ~ 12V output voltage, 500mv / step. PE1.1 supports 5V / 7V/ 9V/ 12V output voltage. The input supports 5V/ 9V voltage.

SFCP fast charging protocol is integrated to support 5V /9V / 12V output voltage.

Integrated vooc fast charging protocol, output support 5V 4A

The layout is reasonable. The high current part has been windowed and tinned to reduce the loss and improve the charging and discharging efficiency.

R8 sets the resistance for the battery capacity.

If the later replacement battery capacity difference is not big, you can leave it alone, if the difference is too big, please replace the resistance again

Calculation formula of resistance value:

Resistance value Ω = (Total battery capacity MAH + 2000) *5/3

For example, the resistance of 30000 MAH should be (30000 + 2000) * 5/3 = 53333 Ω

It can be replaced by a similar resistor, such as 53k.
