NOTE: The Tindie Review site forced me to rate Product, Documentation, and Communication for which I have no experience. I will rate them at a later date.
I just received the two units after waiting one month for delivery - fact, not complaint.
Good thing the cardboard box was well taped, the entire box was dripping wet and only held together by the clear packing tape. It was left by my door on a dry day so it must have gotten wet during shipping - it was thoroughly soaked ! The two Shields were packaged in heat sealed anti-static bags. Unfortunately, one of them leaked and the PCB and the foam the protruding leads were stuck in was dripping wet and some water poured out of the bag on opening - there seamed to be a very small hole in the bag where a pin had poked through.. The other Shield was bone dry. There was minimal corrosion on the wet Shield PCB which looked like the solder flux from the secondary hand soldering of the large connectors - cleaned up nicely with alcohol and I don't expect any issues. The dry one showed no signs of corrosion - only a little left over solder flux from the hand soldering process.
I am overall impressed with the boards and parts and heavily disappointed in the shipper which was China post and then USPS in the states. I think it was wet longer than the time it was in the states so probably got wet on the way from Shanghai where the package originated.
I will post more regarding the operation when I get this project rolling next month.
I ordered RS485-RS422 shield for arduino: https://www.tindie.com/products/Conceptinetics/rs485-rs422-shield-for-arduino/ I received DMX|RDM Shield: https://www.tindie.com/products/Conceptinetics/25kv-isolated-dmx-512-shield-for-arduino-r2/?pt=full_prod_search
I exoect sending the appropriate product as soon as posible by express shipping. Then, I may send the wrong product back on the address the seller want. All of the extra transport cost should be paid by the seller. I also expect that the appropriate product will conatain the documentation or the seler can provide the links where to get it
Looking forward to hearing from you quickly. Regards, Adam
