+ | ====== Description ====== | ||
+ | The total WIO idea has been spread out so far into a nice assortiment of modules.\\ | ||
+ | But hat was all based on the Arduino family.\\ | ||
+ | The new development of he Raspberry Zero, proves, that other producers can do the same\\ | ||
+ | This unit uses the Raspberry Pi Zero as base, which makes it very compatible with the Arduino boards.\\ | ||
+ | The unit was in principle developed to be used in G-track locs.\\ | ||
+ | But doing that there is one thing that should be different.\\ | ||
+ | The Zero takes a few seconds to start up, and a not very solid contact from the rails would cause\\ | ||
+ | the loc to stop for a few seconds.\\ | ||
+ | To avoid that , and also to avoid needing to really seriously clean the rails before we can play outside.\\ | ||
+ | the decision was made to use a chargeable battery inside the loc\\ | ||
+ | But a loc needs more than just motordrive.\\ | ||
+ | The WIOPi-0 has several other controls on board.\\ | ||
+ | This unit is one of the first that also needs SMD components.\\ | ||
+ | WE tried to avoid that as much as possible, but speceially the A/D converter is \\ | ||
+ | no longer in the market in DIL-16, so there was no choice at all.\\ | ||
+ | But this type SO-16 is rather easy to solder with a steady hand and a good quality soldertool.\\ | ||
+ | ====== Features ====== | ||
+ | * Control output for 2 servo' | ||
+ | * Of course output for front and backlights. (led output as standard, but applicable for other items) | ||
+ | * I2C to connect various other options, even a display | ||
+ | * 2 analog inputs for measuring anything that would be interesting. | ||
+ | * RocNet driver on board. | ||
+ | * Serial port to connect an RFID unit like ID12LA. This will abort the need of feed-back contacts and a lot of wiring for that. | ||
+ | * On board H-bridge L6203 for driving motors. | ||
