Hello!
When I started out I was using Atlas / Whitebox carrier boards but I have since designed my own board and no longer need to use these. I was thinking some of you might be interested in purchasing mine. Below is s a list of carrier boards I have. If you are interested please send me a message with which you are interested in and what your offer is. I sent a message to the admin of this forum asking if I could post this but I got no response. Hopefully they are OK with it. I really wish he would open a buy/sale forum.
4 Electrically Isolated USB EZO Carrier Boards
1 EZO Carrier Board *non-isolated*
1 Whitebox Tentactle shield - Arduino shield 4 EZO (all isolated)
1 Whitebox T2 Mini MkII for Arduino 3 EZO (2 of them are isolated)
1 Tentacle T3 for Raspberry Pi - 3 EZO (2 of them are isolated)
If you have any questions or comments please let me know.
