Thanks for the update.

Would your newer TinyCircuits Nordic BLE module be the Nordic Semiconductor nrf52811 with 32bit ARM processor and integrated Bluetooth Low Energy communication?   

Like in this product

I've already (mistakenly) removed R1 on the Motor Controller board and changed the code to match...thinking that it interfered with the Wireling board. 

I want to go the other way, now, so that the product I'm developing is compatible with your "off the shelf" boards with nothing removed.

Thanks for the tip...I try it and let you know.

I mistakenly removed resistor R1 from the Dual Motor TinyShield  ASD2302-R-C - thinking that it may interfere with the Wireling Adapter (I2C wise). it possible to replace R1 (which is shown as 1k on the schematic) with 0 ohms (a dead short jumper) a temporary repair for now?

Many thanks!


General Discussion / Possible Board I2C Conflict

Will the following 2 boards conflict with one another on the I2C bus without changing address resistors (i.e....out of the box)?

 Dual Motor TinyShield  ASD2302-R-C

 Wireling Adapter TinyShield  ASD2022

Willem  et al,

The Rocket Performance Monitor (RPM1) now has the TC eeprom shield for data storage....and it works great! 

During each rocket flight the data (21 separate items) are saved to eeprom for later review on the attached OLED.

Altitude and acceleration data are automatically output for all recorded flights via the USB link to your favorite spreadsheet (CSV output).

The main advantage of going with eeprom rather than the SD Card are:

1.  You don't have to take it out of the rocket (and maybe lose it).

2.  EEProm is cheaper than an SD Card.  Rocket people are price sensitive (so I've found).

Anyway, I've still got a couple of SD Card boards  + SD cards and I'm sure I'll find a use for them eventually, maybe even for the rocket application. 

And the eeprom worked out better than expected.

Thanks for all your help and advice!

After some preliminary model rocket tests, I'm dropping the SD Card in favor of your EEPROM shield.

The reason is that the SD Card can't seem to handle vibration or shock in a model rocket application, while (I assume) the EEPROM shield will (I haven't tried it yet).

While the memory size of the EEPROM is far less than the SD Card, the demanding need is for reliable data storage, which I hope the EEPROM will provide.

I'll get back to the SD Card for other applications, so thanks for all your advice and suggestions about this device!

Thanks All,

Yes...I'm using pin 10 for CS and, also, about the tutorial.

But it looks like I "may not" be giving it sufficient time to respond.

I'll let you know.


General Discussion / MicroSD TinyShield Problem
« on: April 24, 2021, 07:32:57 PM »
I have a MicroSD TinyShield  along with a TinyZero Processor Board.

Do these work together?   

The reason for asking is because the MicroSD indicates pinouts for the TinyDuino Processor Board  and not the TinyZero.

Is there a compatibility issue with the Arduino built-in SPI.h as nothing seems to work in terms of reading and writing to the micro SD card.

Any help will be appreciated.



General Discussion / Model Rocket Locator Beacon
« on: March 02, 2021, 10:53:46 AM »
Has anyone used the 2.4GHz or 433MHz boards for locating objects in the model cars, drones and, especially, model rockets? 

I'd be interested in knowing your results and whether the 2.4GHz or 433MHz board is "best" - read "able to better locate the object"

I'm also looking forward to your experiences with this device, as some non-technical types have asked me how to upload videos to this unit.


General Discussion / ZOE GPS TinyShield Update??
« on: February 18, 2021, 05:02:44 PM »
Any news as to when the ZOE GPS TinyShield will become available?

Any details on same would be appreciated so we can plan on implementations.

How can one charge the battery if the UART (USB port, I assume) is being used for this board? Let me know if I'm off base on this.

BTW, a 20mm x 20mm board would be fantastic!

"With my model rocket application with UART only I have shown that it is not strictly necessary to have access to the I2C, ]but access to both UART and I2C will certainly increase the attractiveness of the new board"

I concur...john
