bt-trx Upgrade v4.1 to v5.0

Tax included
There are not enough products in stock

Attention: Only for customers who already own a bt-trx v4.1 which was purchased in this shop!

By purchasing this article you will get an upgrade of your bt-trx v4.1 to the current version v5.0 - as a small thank you for the early support of the project.
Just send us your v4.1 board by mail and we will transfer the higher quality, reusable components (e.g. the WT32i Bluetooth module) to a v5.0 board.
After a final test you will receive a completely assembled v5.0 board - the v4.1 board remains with us.

Note: Since the built up v5.0 is based on used components, we cannot give any warranty on the built up board.

Please send your board after the order to:
