MDBT42 + breakout

A couple of links to keep some thoughts in one place:

If the price is the same, are there sufficient advantages to wait for a supplier for the nRF52840

https://www.nordicsemi.com/eng/Products/nRF52840

If the need for a breakout is "now", can the two products use the same PCB.

Experience with a nRF52840 Note that the board is Preview

Digi-key: http://www.digikey.com/products/en?keywords=nRF52840 not available "just now"

At this time, http://www.raytac.com/ has no nRF52840 and probably first after Preview.

Bootloader unknown on raytac: I have a raytac module that I can try and hook up to see if it has a bootloader (if I can find it and if I can find a magnifiying glass to be able to see the pins)

What is wanted from the PCB: some input is needed so that the most effective solution for Gordon is obtained.
I have some ideas but I am new "here" so I want to see what the community is asking for ..

It looks like an easier access to pins contra Raytac. I have not examined any other factor for the device. "making all its I/O available via 35 SMD/Through hole 1.27mm pitch pads." THROUGH HOLE: easier access to pins!!!!

This device has GREAT promise, all things being equal with pcb breakout already available.
They also document the need for bootloader : racal is a bit more unknown.
I concentrate a bit on this device. :( price is quite high
Edit: found another price $18 for IMM-NRF52832
https://www.tindie.com/products/hnhoan/n­rf52832-ant-bluetooth-le-arm-cortex-m4f-­30-io/ $12 each for 1000+ :)

Looks like a probable difference of price n­rf52832 to nRF52840 of less than $4 "at the write time"

Hi i-syst, Is there a supplier for the IMM-NRF52832 in Europe that
also has the device in stock? Also the IBK-BLUEIO - Breakout board.
Are there any plans for a IMM- nRF52840 within the next month or so
with a possible price difference within 5 dollars? Best regards Owen

Price difference for basic part (while not knowing what CIAA-R contra other versions means) indicates double price ie difference of about $2 with possible percentage difference for a device of type "ratac" (or other similiar)
http://www.semiconductorstore.com/cart/pc/viewPrd.asp?idproduct=63944 NRF52832-CIAA-R $2.89
http://www.semiconductorstore.com/cart/pc/viewPrd.asp?idproduct=65645 NRF52840-QIAA-R $4.44
