New CR-1,2,3 Kits for Kids


 

开云体育

Guys,

Merry Christmas! Now you can see the photos of the whole set of three (forget about the new camera battery and charger):

The kits are co-designed with a teacher in Beijing for youngsters in China for regional and national contests. We are glad to offer kits to our group members as well.

CR-1: Audio Morse code trainer with volume and tone controls (the on-board speaker is not a part of the kit)

CR-2: FM transmitter of 87.5-88.7 MHz, five frequencies, and it can sit on top of the CR-1 to support voice or morse code transmission. Without the external antenna, it can transmit to the next room

CR-3: FM receiver in two modes, one for general coverage of 87-108 MHz, and the other is for 87-89MHz to work with CR-2 (a wire antenna is supplied, but the on-board speaker is not a part of the kit)

The PCB size is 60 x 90 mm.

The early bird price is 45 USD for all 3 kits including air shipping. I can ship in 2 weeks before Chinese New Year. The next batch will be after the new year holiday. Please PayPal directly to rongxh@... and leave your ship to address and telephone number. If you wish to buy 2 kits, the price is 88 USD.

Thanks,

Adam


 

Hire much for the set of 3?

Hi Noel,

The price is 45 USD for the set of 3 kits, and 88 USD for 2 sets. The SMD chips are pre-soldered, so don't worry. You need to prepare total 8x AAA size batteries. You can use headphone if you don't have small speakers on hand.

Thanks,

Adam

Hi,

The kits before Chinese New Year are ready to ship now.
I suspect the small SMD IC is already soldered to the board?

Holiday greetings,


 

Hi Paula,

They were already soldered.
