Here are some fotos taken of the Dev Shield.
- When parcel arrived, Dev Shield bag had been opened but nRF52-DK bag was sealed
- During Dev Shield assembly, the JTAG header was not aligned when soldered
- The header misalignment and cracked header was observed when Dev Shield initially placed on top of the nRF52-DK.
==> Dev Shield connectors were not aligning with nRF52-DK connectors
==> Observed cracked header and misaligned JTAG header
==> Did not want to wait 2 to 3 weeks for a new Dev Shield so I gently inserted Dev Shield onto nRF52-DK.
==> Even though header cracked, visually, the pins looked like they were still making contact so decided to go ahead and mount a Ruuvi Tag onto the Dev Shield and start learning the Ruuvi environment (want to understand code with long-term objective of adding sensors to the Tag).
==> Do not want to mount another Ruuvi Tag onto the Dev Shield until we F/A why the Tag that was mounted onto the Dev Shield is not properly functioning
Couple of comments:
- Ruuvi should not ship returned/used parts as “new” parts … especially parts used for development purposes
- Dev Shield PCBAs should be cleaned after hand soldering. A lot of flux about soldering joints … some fluxes can cause long-term reliability issues … do not know what flux was used during hand soldering
- Don’t know if this is associated with some of the issues that I have been experiencing but it would be nice if you send a new Dev Shield to replace the defective shield that was originally shipped
