Babur had the same with a combo GPS/GLONASS chip which I've seen later variants of with Beidou and these RX/chipsets barely weigh a few grams.Ok so I will separate my thoughts in separate posts for clarity.
Taimoor is clearly a development of the Ra'ad 2. However, we should not think this is a simple progression. Ra'ad 2 is a nuclear delivery system so it a) has no need to be pinpoint accurate, and b) needs as much space as possible for its payload. This tells us that Taimoor very likely has a smaller space for its warhead. The weight of the seeker isn't huge (4 kg from above specs) but the space that the seeker takes up is significant. Regardless, for the kinds of mission Taimoor is meant for, this loss in boom matters naught.
Regarding what it takes to "add a seeker":
Ra'ad 2 has a guidance system based on INS (maybe TERCOM/DSMAC etc) and the entire flight software is designed for it. Now you add a seeker. You need to add some software and memory to be able to recognize targets. You need a system to feed it target picture before it is launched. Secondly, you need to add an end-game guidance based on the seeker inputs. This is an entirely new phase of flight, and what lets it hit targets so accurately. You need lots of simulation and testing to get this right. 4 km is more than enough range for this seeker. It only needs to track the target in the endgame. It is essentially a Ra'ad2 the rest of the way. The legacy guidance and navigation gets you in the vicinity of the target, and the new seeker+end-game guidance gets you to the target.
The entire board on its own isn't the weight it's the overall packaging and spec cables.
The overall guidance chipset would be the size of a few tuc biscuits weighting in at barely a pound and then the I/O peripherals, cables and so on are heavy, bulky octopuses all around it.
