Hi,  
I have a few questions about the upcoming LoRa Notecard:

1. The STM32WLE5 is a transceiver; will the LoRa Notecard enable the ability to transmit and receive from the Notecard?
2. Will the LoRa Notecard be able to be used without a LoRa gateway? For example, for communication between 2 LoRa Notecards?
3. The STM32WLE5 states that active-mode RX uses 4.82 mA and active-mode TX uses 15-87 mA. The Notecard power usage table specifies a power supply capable of 250 mA. Can we expect the power requirements to match the STM32WLE5 published specs?
4. The STM32WLE5 is a microcontroller. Will a separate microcontroller still be required to interact with the LoRa Notecard like the other Notecard products?
5. What is the expected price of the LoRa Notecard? Edit: [Looks like $10](https://shop.blues.io/collections/notecard/products/notecard-lora).
6. When will the LoRa Notecard be available for purchase?

Thanks!

Hi @icecats,

Happy to answer these question as best I can:

> 1. The STM32WLE5 is a transceiver; will the LoRa Notecard enable the ability to transmit and receive from the Notecard?

Yes, you can both send and receive data with the Notecard LoRa, just like other Notecards.

> 1. Will the LoRa Notecard be able to be used without a LoRa gateway? For example, for communication between 2 LoRa Notecards?

No, all communications must go through a TTN gateway.

> 1. The STM32WLE5 states that active-mode RX uses 4.82 mA and active-mode TX uses 15-87 mA. The Notecard power usage table specifies a power supply capable of 250 mA. Can we expect the power requirements to match the STM32WLE5 published specs?

I need to follow up on this internally, but I believe the 250mA is a “safe” estimate for spikes when the Notecard boots. I would expect normal power requirements to be very similar to what is documented for the STM32WLE5.

> 1. The STM32WLE5 is a microcontroller. Will a separate microcontroller still be required to interact with the LoRa Notecard like the other Notecard products?

Yes, you will still need a separate microcontroller.

> 1. What is the expected price of the LoRa Notecard? Edit: [Looks like $10](https://shop.blues.io/collections/notecard/products/notecard-lora).

Correct.

> 1. When will the LoRa Notecard be available for purchase?

It’s looking like December, but nothing official beyond that.
