It also can connect to any network 2G-3G-4G whichever is available (sorry no 5G yet ūüėČ ).

Once the prototypes are ready and check we are preparing Crowd Supply campaign for it! Hint Fits perfect to LoRa-GATEWAY and allow connection where no wires and optics like mountain hubs, remote areas etc.

You can post here or retweet/share/boost on Twitter/Facebook/Mastodon/Diaspora and in Monday we will let Random.org to decide who will win one of our new eduArdu educational board.

Have a nice weekend!

UODATE 22-04-2019: Random.org selected @netsigi as winner!

 

Ever wondered how much current your USB devices use and how stabile is your USB voltage? Now you can measure!

USB-POWER

Some USB devices like 3G modems, WiFi etc in active mode draw lot of current and cause problems, to monitor the current consumption and how stabile is your USB voltage you can use this USB-POWER-METER.

The consumption is measured and displayed with 10mA accuracy. Voltage with 10mV accuracy.

MOD-RFID1356MIFARE NFC / RFID reader writer for MIFARE 13.56Mhz tags

MOD-RFID1356MIFARE

MOD-RFID1356MIFARE is re-design of our popular RFID card readers. It’s based on NXP PN532 chip and can read and write in ISO/IEC 14443A/MIFARE tags.

Like with MOD-RFID125 and MOD-RFID1356 it’s extremly easy to use. It connects via USB to any computer and creates HID keyboard or CDC serial port. There is no need for any drivers and switching between the modes is very easy with one push button.

WiKi description explains how to use. Read distance is up to 15 cm for ISO cards. We will stock soon 4 different types of tags: ISO card, clamshell, keychain and adhesive sticker.

AR9271 chipset is the only one with Open Source Firmware and Linux drivers. It has build in Kernel support since Kernel 2.6.35 so if you want to run GNU/Linux clean of non-free binary blobs with unknown content this is the device for you. It will work with your desktop PC, laptop, or SBC like OLinuXino and Raspberry Pi etc.

MOD-WIFI-AR9271-ANT samples are tested and proven to work with all our OLinuXinos and have excellent WiFi reception due to the huge antenna they came with. We have pending order and they will be in stock very soon.

New KiCAD OSHW PCB project – Getting rid of FTDI – BB-CH340T USB to Serial converter

BB-CH340T-3

Many of you probably remember the FTDI nasty drivers they released just to mess up with the FTDI clones.
This caused lot of trouble to people who use FTDI devices, we have been also affected.
We try to buy FT232RL from local distributor and they had no stock, then we look around and found the chips from other supplier, but unfortunately we got clone FTDI chips.
We made production with these chips and sent boards to customers, then at one point of time we start to get complains (only from Windows users) that boards stop working.
All these windows users were affected by the evil drivers released by FTDI which make VID/PID as zero if the chip is recognized to be not FTDI original.

We try to help our customers who have been affected on our forum and got nasty message from FTDI lawers to remove all the help instructions from our forum and pull back all boards which use these clone FTDI chips from customers and distributors. WTF?

No wonder from this moment we took decision to avoid dealing with this cheeky and nasty company as much as possible. Re-designing all our boards which were unfortunate to use FTDI chips.

CH340T is nice alternative to FTDI chips and have same features and even more, but cost exactly 1/10th of FTDI chip price.

BB-CH340T is nice small board which takes power from USB and can provide 3.3V and 5V to target together with Serial Tx and Rx (transmit and receive) signals and GND.

Note that by default neither 3.3V neither 5V is selected.

BB-CH340T is specially made to be used easy with breadboard. The design is open source hardware made with KiCAD and files are on Github under Apache 2.0 licensee.
