Interestingly, one or more of the resistors I ordered is classified as “Hazardous” and now my shipment will take up to 3 weeks to be delivered.
The Step sticks will be (substantially) delayed.
What do we learn from this? Do NOT use 0402 resistors in designs if you can help it. They do look very cute, and are very inexpensive in bulk, but almost impossible to get in hobby quantities. Lesson learned.
