Amblit Technologies purchased the SunFounder Pico Robot Car Kit from Amazon in November 2022 for $89.99. A description of the kit can be found here. The kit includes a Raspberry Pi Pico controller and is programmed with MicroPython. Two (2) rechargeable batteries (3.7v 18650 button top) and a battery charger must be purchased separately for under $30. This is a fairly common battery and is used in different kits (see the Robot Power Sources for some recommendations of where/what to purchase).
We have not inventoried or started the assembly of this kit yet.
