On my variant (tz1/github.com has the code), to get around the long periods when the SD can be busy, I added a Microchip 32k byte SPI SRAM and would use that to buffer the incoming serial data. There is aQuestion by: admin on 2018-12-18 02:39:21
Hi.The firmware within this product has been soldered,so we can't change the parameter about it.Answer by: admin on 2018-12-18 02:39:21
Can I assume a voltage of 12 volts is safe for serial input, or is it limited to 3.3v or 5.0v? I'm not sure if "input voltage range: 3.3 to 12V" refers to powering up the device, or serial communication.Question by: admin on 2018-12-18 02:39:21
Dear Phil Wade.For the steady hardware , you can't read 134.2KHz tags.Answer by: admin on 2018-12-18 02:39:21
When I READ with the device I see spurious "." (0x2E) characters at the end of each line. However CAT confirms that these spurious characters are not there in the file itself. Check this:

Hello, i'm very interested in this product! There are some things I would like to ask first.
The Openlog from Sparkfun has problems with highers baud rates, like 115200, which cause it to lose characters. They claim that the problem is because the bQuestion by: admin on 2018-12-18 02:39:21

Hi, I've purchased two SDloggers from SeeedStudio, and one of them outputs "Type any character to start" via UART when power up, and starts interval logging something (ADC value?) in CSV format to SD card.
Another one outputs initializizing status,Question by: admin on 2018-12-18 02:39:21
Sorry , it can't . You can add a LED indicating when RFID tag is removed via judge if hardware serial have data input.Answer by: admin on 2018-12-18 02:39:21
I've had this board for a few months now. I do not use the stock firmware. I used the arduino environment to write some firmware for my needs. This is nice with the atmega644, 2 serial ports, I2C port, and a few analog ports broken out. This has simpliQuestion by: admin on 2018-12-18 02:39:21

As written in the Title i think it would be a nice feature if there where a small RTC clock chip on the Board (for file creation date and time). Also i looked at the code and it seems there is no possibility to log non standard Baud Rates (10400 comesQuestion by: admin on 2018-12-18 02:39:20
Hi Robert for special feature like logging non conventional Baud Rates I recommend you HydraBus with latest firmware, of course the firmware is fully open source and can be customized to your needsAnswer by: admin on 2018-12-18 02:39:20
Hi Magnus Karlsson,
Where could I find the hex files for the lastest version of the SD Logger firmware ?

I'm looking at the Github repository for the SDLogger as well as the sales page. I have two questions:
1. Does my SDLogger drop into a low power mode like an OpenLog running v3.11?
2. Does my SDLogger automatically flush buffers after 1/2 secoQuestion by: admin on 2018-12-18 02:39:20
Sorry, we do not sell both of connectors separately. If you really want a pcs to put it in your project, maybe you could get an JST 2.54mm to 2.0mm Converter Pack, just cut the cable. (Answer by: admin on 2018-12-18 02:39:20
hi, i just purchased this & it's been great so far. I'm looking to use this on a very low power application. So far what i've seen is the unit runs @ about 8mA without really doing anything. I've read that Sparkfun's openlog had similar results until t
Hi, thanks for your interest in this product. We only distributor for this product, it work with the most 125k RFID card without special security such as the 125k RFID card we are selling, but we not sure that if it will compatible with HID Prox II car
I need to build some small and low power consumption data loggers.
I have to log data from a couple of I2C sensors (LSM3030DLH from Sparkfun and a Pressure sensor) and from an analog sensor (low sample rate).
Furthermore I have to time stamp each
