The all-through-hole kit has been discontinued. We are only offering semi-assembled kits right now. Most of the passive components like resistors and capacitors are SMT and pre-soldered onto the boards, the microcontroller and Ethernet controller are left for the users to solder. So while it’s not all through-hole, it still provides some flexibility if you want to change / upgrade the microcontroller and so on. Additional details can be found on this blog post:
