I'm using a 21pin HM7000-TXS (sound) with HM7070 power bank. This is my first 21 pin chip installation. Installation. The instructions could be enhanced to show the socket ON THE TOP once the chip has been installed. For those of us old school electronics people, it is possible to try to install the board upside down if you think the socket should take the pins directly, as opposed to the socket being on the top when installed with the pins passing through the etched board to reach the socket on the other side. Whether it would have worked or blown up is not known as I didn't try, but I will admit that it didn't look right so I came back to the installation after a sleep to reconsider.Both the speaker and the power bank plugs and sockets are also not totally clear in terms of which way up they need to be fitted. Colouring the pictures to show the black and red wires could help here, but also using a plug with more obvious differences in terms of which way up it goes would also be a benefit. Using +2.00 reading glasses with an additional magnifying glass helped here (Please consider the average age of the grandparent trying to help their grandchildren when designing small items).
