Lieferung ist sehr schnell angekommen, sehr gute Qualität, funktioniert einwandfrei. Kan das Board nur weiterempfehlen

I love these boards. With 8MB of PSRAM they run quite large micro-python applications very easily. The 18650 battery holder on the back is great for low power data collection projects that I make. The on-board buttons for reset and boot are very convenient too. When they are on offer I always order a couple!

Awesome product, the ability to use a wrover chip and not have to worry about it’s power supply is perfect! 18650s are becoming more and more popular anyway so a handy battery to have.

Fast delivery, good packaging, working fine, but be aware that the battery compartment will only fit only shorter 18650 batteries without protection

good quality and works as expected

Very good

great

as promised

cheaper than trying to buy all the components separately and does the job perfectly
