I'm trying to find an appropriate wall charger to power my Beaglebone Green Wireless (BBGW) through Micro-USB port.

Wall is 220v 50Hz.

Hardware Overview reveals a TPS65217C Power Management IC (PMIC).

Parameters

Iout (Max) (A) 1.2

Features

2-A Output Current on Power Path
Linear Charger; 700-mA Maximum Charge Current

Confused. How many Amps are enough?
(α) 5V, at least 1.2A
(β) 5V, at least 2A
(γ) 5V, at least 700mA

  • It's not clear why you are asking. Why have you quoted "Iout"? What is the total current required by your modules? You just need a PSU that is capable of providing at least that current. – Transistor May 04 '21 at 09:07
  • @Transistor (1) I've quoted those phrases but have no idea what they mean. This is exactly why I'am asking here. (2) I don't connect anything to BBGW at all. Just the board alone. How many amps do I need? – Darren Ng May 04 '21 at 09:29

    I can't see anything on the BeagleBone website that quotes the current consumption of the device. You should ask on their forum, "I am selecting a 5 V PSU for my BeagleBone xxx. What is the maximum current requirement of the device?". – Transistor May 04 '21 at 11:16
