Hi Guys, I’d like to introduce my new demo node, no wire, just battery powered, Arduino Mini 3.3V 8Mhz. I created a demo for a customer with a fully Temperature Humidity sensor (I2C SI7021) with Battery Level Monitor, and here it is. [image] [image] I know it’s not the smallest node, but what th…

[image] disk91: There nothing more than a ATMEGA328P and a RFM95 Can you provide a picture of the actual board ?

[image] bluejedi: For ESP32 I have not found any similar option which fits a normal breadboard Maybe this one: [image] Adafruit HUZZAH32 – ESP32 Breakout Board Squeeeeze down your next ESP32 project to its bare-bones essential with the Adafruit HUZZAH32 Breakout. This breakout is …

Nice, thanks! Unfortunately a schematic diagram for what is on the board seems not (yet) available.

you can find the board here : https://www.tindie.com/products/IOTMCU/lora-radio-node-v10/ version 868mhz. Before you ask, the DCDC converter is not the reason. I also make measure on the 3.3V directly with a 3.3V source.

[image] LoRaTracker: There nothing more than a ATMEGA328P and a RFM95 So quite a few more components. Before you ask, the DCDC converter is not the reason. I also make measure on the 3.3V directly with a 3.3V source.` So the ‘DCDC converter’ (regulator ?) was removed or otherwise disconn…

No, the DCDC is connected but if I measure current before or behind the DCDC I get the same result.

I would also suggest that unless you want to re-work that board, by removing or replacing the regulator, your never going to get sleep current below (typically) 90uA. Check out the datasheet of the regulator used …

GREAT NEWS ! [image] CH2I ULP node library open source! LMIC [17%20AM] @Charles , CH2I , has decided that he will open source his ULP node library and that is very good news for all of us ultra low power users !! [IMG_6084] Because his library is only used for his cus…

Hello Andris, CAn You share Your PCB files for Sigiot low Power LoRa node. Best regards, Dejan

Hello, I have a project with a communication Lora, and different sensors with low consumption. But with an arduino pro mini + rfm95w, I don’t have enough space on the microcontroller: text section exceeds available space in board Le croquis utilise 33216 octets (108%) de l'espace de stockage de p…
