Étape 4
Let' see what we got
-
As you can see this is the 1.0 Version, how cute.
-
There are some test points to find out whats the problem: BATT (For to check the Battery votage is present and how much is it), 5V USB Power Supply, SDA & SCL Communication Points, and a RESET Piont (Maybe with a Pull Up push button resistor circuit).
-
An Elecetrolytic Microphone (Note: this one is into each bluetooth buddy).
-
The brain is open: Airoha AB1524 Truly Wireless Bluetooth IC.
-
Battery Cables Positive, Negative, and Sense.
-
LP & LN Speaker Connection (those speakers are inside the tube) very small... and unpower.
-
A very Small 55mAh LiPo Battery.
