Quectel SC20 Smart LTE Modules with WiFi, BLE and GPS Run Android 5.1

Google may just have released Android Things operating systems for IoT applications, but its big brother – Android – has already gotten into some other IoT systems such as Quectel SC20 module powered by a Qualcomm processor and supporting LTE, WiFi, Bluetooth LE, and GNSS functions. Quectel SC20 comes in different flavors to cater for various markets, but all module share most of the same specifications: SoC – Unnamed Qualcomm processor System Memory – TBD Storage – 8GB flash Cellular Connectivity – FDD LTE, TDD LTE, TD-SCDMA, EVDO/DCMA, WCDMA, and GSM; antenna: MIMO 2×2, supports Rx-diversity Other Wireless Connectivity WiFi – 2.4GHz 802.11b/g/n (SC20-CE/-W); Dual band 802.11a/b/g/n/ac (SC20-E/-A/-AU/-J) Bluetooth 2.1+EDR/3.0/4.1 LE GNSS – GPS, GLONASS, and BeiDou Interfaces LCD – 4x lanes MIPI-DSI, 1.5Gbps each, HD (720p) @ 60fps Camera – MIPI-CSI, up to 1.5Gbps per lane, supports two cameras 2-lane MIPI_CSI for rear camera, up to 8MP 1-lane MIPI_CSI […]

Arduino MKRZero is a Smaller Arduino Zero Board

Arduino Zero was unveiled over two years ago with an Atmel SAMD21G18  ARM Cortex M0+ MCU in Arduino Uno Rev.3 form factor, the company has now launched Arduino MKRZero with the same MCU but using the much smaller Arduino MKR1000 form factor. Arduino MKRZero specifications: MCU – Atmel/Microchip SAMD21 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash (8KB for bootloader) External Storage – micro SD slot Digital I/O Pins – 22x GPIOs with 12x PWM, UART, SPI, and I2C, 8x external interrupts Analog Pins – 7x analog inputs (8/10/12-bit ADC), and 1x analog output (10-bit DAC) DC Current per I/O Pin – 7 mA USB – 1x micro USB port for power and programming Debugging – USB via Atmel’s Embedded Debugger (EDBG) on-board debugger, and JTAG Misc – reset button, 1x LED (pin 32), 32.768 kHz RTC Power 5V via micro USB port […]

Banana Pi BPI-M64 & BPI-M2 Ultra Boards PDF Schematics Published

SinoVoip has recently released PDF schematics for both of their Banana Pi boards, namely BPI-M64 board powered by Allwinner A64 processor, and BPI-M2 Ultra board based on the latest Allwinner R40 SoC with an on-chip SATA interface. For most boards on the market, this should not be news, but SinoVoip does not always release schematics in a timely manner, so you may want to be noticed when it happens: BPI-M64 schematics – https://bananapi.gitbooks.io/bpi-m64/content/en/bpi-m64schematicdiagram.html BPI-M2 Ultra schematics – https://bananapi.gitbooks.io/bpi-m2-ultra-open-source-single-board-computer/content/bpi-m2ultraschematicdiagram.html The clear benefit of BPI-M2 Ultra is the presence of a SATA connector NOT implemented via a slow USB 2.0 to SATA bridge, but instead directly through the SATA interface of the R40 quad core processor. As for BPI-M64 ($46), it can be compared to Pine64+ with 2GB RAM and a WiFi module ($39), and despite the higher price it does come with some benefits like adb over OTG working, it is […]

$24 Winkel Arduino Compatible Board Includes WiFi, Bluetooth, 2.4 GHz RF, and an RTC (Crowdfunding)

There are plenty of Arduino compatible boards with WiFi based on ESP8266 WiSoC going for around $5 to $10, and with ESP32 processor, we are starting to have $15 to $20 boards with both WiFi and Bluetooth, but while ESP-IDF SDK has been progressing nicely, some parts of Bluetooth functionality are still not implemented. Winkel board offers an interesting alternative by offering WiFi, Bluetooth, 2.4GHz ISM, and an RTC for $24. Winkel board specifications: MCU – Microchip/Atmel ATmega128 MCU @ 16 MHz with 128KB flash memory, 4KB SRAM, 4KB EEPROM Connectivity WiFi 802.11 b/g/n via ESP12E module based on ESP8266 Bluetooth 2.0 + EDR via HC-05 module RF Radio – NRF24l01 2.4 GHz ISM radio. (Note: It might be possible to use it for Bluetooth LE connection, see here and there). I/Os (through both Atmel MCU and ESP8266) 38x Digital I/Os 7x PWM Digital I/Os 8x Analog Inputs USB – […]

Linux 4.9 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux 4.9 on Sunday: So Linux 4.9 is out, and the merge window for 4.10 is thus open. With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into Xmas food prep, even that date might be questionable. I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last […]
