MicroPython running on ESP8266-EVB driving MOD-IO and MOD-IO2 relays

New tutorial how to use ESP8266-EVB with Micropython and to switch on/off relays and read ADC values on MOD-IO2 from MCHobby.be

New Product: Optical Fingerprint sensor SNS-FINGERPRINT adds fingerprint recognition to your next project

SNS-FINGERPRINT is optical fingerprint sensor which will make adding fingerprint detection and verification very simple. Inside there is DSP chip that does the image rendering, calculation, feature-finding and searching. You can teach the sensor for fingerprint images and up to 1000 images can be stored in the internal Flash memory. There’s a red LED in the lens that lights up during a photo so you know its working. In image search mode the sensor compare the current scanned image with the stored database and if images match it sens index number of the stored image which match the current scanned fingerprint.All communication is done by UART.

ESP8266 IoT firmware plug and play detects if SNS-FINGERPRINT is connected to UEXT uart so you can make wireless door access system very easy using just Javascript programming.  We also have demo in Arduino C++ and OLinuXino Python3 so you can access this sensor with any of our development boards.

 

New Open Source Hardware Product in stock: ESP8266-EVB-BAT with build-in LiPo charger and step up converter

ESP8266-EVB-BAT is further enhancement of ESP8266-EVB. It’s with dimensions 51.3 x 56.6 mm and with shape to fit in Hammond Box 1593KBK.

The version of this board in box is named ESP8266-EVB-BAT-BOX is perfect if you want to make handheld WiFi gadgets :

The relay connector is Wago two part connector, which allow easy to connect and disconnect.

As name saysESP8266-EVB-BAT is exclusively designed to may work on battery. It have input voltage sense, build-in intelligent charger for LiPo battery and battery connector, so you can use any of our existing LiPo batteries for your next handheld WIFI device.

The battery charges can charge with 200 or 400mA and selectable by SMT jumper on the board. On board there is also step-up converter which provide 5V power supply to the relay and module. So if battery is attached and external power is applied the charger will charge the Lipo battery to maximum, then if external power is cut the battery will automatically supply power to the board. GPIO16 input is connected and sense external power supply.

ESP8266-EVB-BAT have two connectors: UEXT connector which allow Olimex UEXT modules to be connected and driven by IoT-Firmware using simple HTML/JavaScript and CON1 where all ESP8266 resources are available together with charger circuit signals and power supply.

 

15 New Products in stock

We have 15 new products in stock! Above on the picture you see KBD-BT1 which is 3-in-1 Wireless Keyboards + Touch panel mouse + Laser pointer. This keyboard works with all our OLinuXino boards both under Android and Linux and have re-chargeble LiPo battery which can be charged on any USB port or adapter with USB mini cable.

KBD-BT2 is bigger version, gamer edition, with bigger LiPo battery, many functiona keys:

again it’s compatible with any OLinuXino both under Android and Linux, but you can use it with any Android dongle or your smart TV to browse internet and work from distance.

USB-BT4 is super duper mother of all Bluetooth dongles. It supports Classic Bluetooth 2.0, High speed Bluetooth 3.0 and latest Bluetooth Low Energy 4.0, so you can use it with nRF8001 and any other Bluetooth device which is 2-3-4 compatible. The dongle comes with mini CD for WIndows installation. Linux distributions with kernel 3.11 or higher should have implementer BLE 4.0 support, for the moment support for OLinuXino is not available as our kernel is 3.4, but we hope to have support soon:

 

We got two new ECG electrodes. ECG-SCUP is suction cup electrode compatible with SHIELD-EKG-EMG when used with SHIELD-EKG-EMG-PRO cable and snaps directly to it:

ECG-CLIP is clip electrode compatible with SHIELD-EKG-EMG when used with SHIELD-EKG-EMG-PRO cable and snaps directly to it:

AOY-T1-6D, AOY-T-I and AOY-T-B are soldering iron tips for AOY-SLD936 and AOY-SLD936A soldering stations:

AOY-B002 is 60W/24V spare handle with ceramic heater and soldering tip for AOY-SLD936A

AOY-B004 is 35W/24V spare handle with ceramic heater and soldering tip for AOY-SLD936

AOY-C001, AOY-C008 and AOY-C010 are spare ceramic heaters for AOY-SLD936, AOY-936A and AOY-SLD463 soldering stations:

 

CHN-TWZ2MM is lower cost but still good quality tweezers alternative to PGC-00SA professional tweezers:

 

CHN-TWZ1MM is ultra low cost amateur quality tweezers which are good for pick and place of SMT components but can’t be used for component lead forming like CHN-TWZ2MM and PGC-00SA.

 

New Product in stock: MOD-USB3G

MOD-USB3G is 3G wireless modem with these features:

• • SIMcard connector
  • microSD card connector where cards up to 8GB can be put and will be visible as mass storage
  • HSUPA/HSDPA/WCDMA-850-1900-2100Mhz
  • GSM/GPRS/EDGE 850-900-1800-1900Mhz
  • HSUPA Dn 7.2Mbps Up 5.76Mbps
  • HSDPA Dn 7.2Mbps UP: 384kbps
  • EDGE Dn 236.8kbps
  • Support Voice and SMS
  • USB
  • Supported by A13/A10S/A20 Debian and Android
  • Size 88x26x12mm

We tested MOD-USB3G and it works with all A13/A10S/A20 OLinuXino we have both with Android and with Debian images. Now you can have mobile Internet connection with good speed everywhere you go. MOD-USB3G will work with your laptop and desktop computers too.

The low cost EUR 15 makes all these old GSM/GPRS solutions with Telit/Simcom etc look expensive, slow and obsolete.
