Bought this from B&M Bargains in the UK. The unit was in a discounted, £25 down to £15 (who would pay £25?!) area and labelled as having a missing remote. I noticed it was also missing a power supply so asked for a further discount and got it for £7.50. I later realised this version doesn't come with a remote, so only the PSU was missing :o
Anyway, inside it's a BK7231N. The RX1, TX1, RX2, TX2, GND, CEN, VCC are all labelled nicely on the back of the PCB. This is probably the easiest dump/flash I've performed so far. I found a 12v adaptor with a fitting barrel connector so used this as my power source rather than using the VCC from USB-TTL adaptor. Only GND, TX1, RX1 and CEN used when flashing.
It's clear from the unsoldered 3.3/GND/IR that I could add an infrared sensor, perhaps like https://www.youtube.com/watch?v=KU0tDwtjfjw
In researching the PCB I found this EKF-branded product with the same board. The packaging and content look very similar but this one has IR and a remote.
