Skytraq PX1122R Tiny Multi-Band RTK GNSS Module Offers Centimeter Accuracy

Skytraq PX1122R Multi-Band RTK GNSS Module

Several years ago Skytraq introduced NavSpark mini, a tiny (17x17mm) GPS module, that sold for $6. I got one and wrote a post explaining how to get started with the GPS module using GNSS viewer program. The company contacted me again today, as they’ve now launched an even smaller module Skytraq PX1122R measuring just 16x12mm, supporting GPS, Galileo, GLONASS, and Beidou signals, as well as Real-time Kinematic (RTK) relative positioning technique that allows for 1-3cm positioning accuracy. Skytraq PX1122R RTK GNSS module key features & specifications: Chipset – SkyTraq PX100 Phoenix GNSS chipset Supported GNSS standards & bands – GPS L1/L2C, Galileo E1/E5b, Beidou B1I/B2I, GLONASS L1/L2, QZSS L1/L2C Integrated RTK with 1cm + 1ppm RTK accuracy in seconds (under 10 seconds) Up to 10Hz quad-GNSS RTK update rate Base or rover mode configurable Serial Interface – 3V LVTTL level 24x castellated holes with UART, RF input, 1PPS, Reset, 3.3V, […]

Sony CXM1501GR ELTRES LPWAN Module Promises a Range of over 100 Km

While there are many LPWAN (Low Power Wide Area Network) standards, three appear to dominate the news namely LoRaWAN, SigFox, and 3GPP NB-IoT/eMTC. They all offer long range and up to 10-year of battery life enabled by the use of low bitrate which is fast enough to send sensor data. We can now add another LWPAN standard to the list, as Sony has developed ELTRES wireless communication standard suitable for IoT networks, and announced their CXM1501GR ELTRES module with a range of over 100km, even while traveling at 100km/h. Key features and specifications: ELTRES Connectivity Antenna radiated power – 20mW Communication direction – Uplink only Frequency – 923.6 MHz to 928.0 MHz (23-channel frequency hopping) Main modulation system – π/2 Shift BPSK Sub-modulation system – Linear chirp modulation Transmission system – Four repeated transmissions of 0.4 sec or shorter packets Reduction of interference with other systems – CSMA (Carrier Sense […]

Aconno Bluetooth Beacons Come with Various Sensors, Nordic Semi nRF52 BLE SoC

We first covered products from Aconno is 2017 with their Bluetooth LE development board powered by the company’s ACN52832 BLE module based on Nordic Semi nRF52832 ARM Cortex-M4 multi-procotol wireless SoC. Since then they’ve launched several small Bluetooth beacon modules based on ACN52832, and the company has what they call a presale promotion until May 21st, but it looks really like a group buying event for their existing BLE modules where the price goes down as more people purchase modules. Six Bluetooth modules are offered: acnSENSA multisensor Bluetooth tag with temperature, light, humidity, barometer, accelerometer, magnetometer, gyroscope acnBEACON programmable Bluetooth tag acnACT BLE beacon with button and RGD LED, magnetometer, phototransistor acnNFC programmable Bluetooth tag with NFC tag emulator acnRANGE distance measuring beacon with time-of-flight sensor acnFIND Bluetooth smart tag with LED, sound and accelerometer All modules come with a replaceable CR2450 battery, and IP65 enclosure. Pricing currently ranges from […]

Sipeed M1 RISC-V Computer Vision Module Features Kendryte K210 Processor

Just a few days ago, I wrote about Kendryte KD233 board featuring Kendryte K210 dual core RISC-V processor, with some fairly detailed documentation, public links to toolchains and other tools. and going for $50. But the team behind LicheePi boards informed me that they also made their own K210 module called Sipeed M1 and selling on Taobao for the Chinese market, as well as on Yoycart for $10.89 plus shipping for the oversea market, and you’ll find a devkit with a dock board for about $24 and up depending on options. Sipeed M1 module specifications: SoC – Kendryte K210 dual core 64-bit RISC-V processor @ 400 MHz with KPU CNN hardware accelerator, APU audio hardware accelerator, 6 MB general purpose SRAM, 2MB AI SRAM memory, and AXI ROM to load user program from SPI flash Package – 72-pin (25.4 x 25.4mm) But you’ll probably want to get start with M1 […]

Turris MOX is a Modular Router with WiFi, SSD, LTE Modem, Ethernet, and SFP (Fiber) Modules (Crowdfunding)

The makers of Turris Omnia router – powered by a Marvell ARMADA 385 processor and running Turris OS based on OpenWrt – have been working a new product: Turris MOX modular router which can be extended with mPCIe add-on cards for LTE, SFP cage, M.2 SSD, and so on. They will soon launch an Indiegogo campaign for it, but in the meantimes, CZ.NIC association has a pre-campaign for a $69 MOX access point with dual band WiFI card, and intended for Turris Omnia users. The full details are not available, although we can find out a little more through root.cz and the video embedded below. The system is comprised of a basic MOX A module powered by a dual-core Armada 3720 processor coupled with 512 MB RAM, as well as USB 3.0, Gigabit Ethernet, and an I/O expansion header with GPIO, SDIO, UART and I2C.

ALB32-WROVER is an ESP-WROOM-32 Compatible Module with 32 Mbit PSRAM, up to 128 Mbit Flash

ESP-WROOM-32 is one of the most commonly ESP32 WiFi + Bluetooth module, and does the job for many applications. However, it only includes 4MB (32Mbit) flash, and no external PSRAM, while Espressif ESP32 chip itself supports up to 128 Mbit (16MB) NOR flash and up to 32Mbit (4MB) PSRAM, so for applications demanding more resources (e.g. MicroPython), or for initial development it would good to have a module maxing out memory and storage capabilities of the chip. Analog Lamb ALB32-WROVER does exactly that with 32 Mbit PSRAM, and 32 to 128 Mbit flash, in a form factor compatible with ESP-WROOM-32 module. ALB32-WROVER specifications: WiSoC – Espressif ESP32 (Rev0?) Wi-Fi and Bluetooth combo chip External Memory – 32Mb PSRAM Storage – 32, 64, or 128Mbit Flash Dimensions – 18 x 25 x 3 mm Compatible with ESP-WROOM-32, except for GPIO16 & 17 (used for PSRAM) It’s very odd the company claims the […]

Aconno Bluetooth 4.0 & 5 IoT Development Board Features an nRF52832 or nRF52840 Module, an e-Paper Display, Sensors and More

Bluetooth 5 is the latest iteration of Bluetooth with up to four times the speed and twice the range of Bluetooth 4.0 LE, and so far apart from Puck.js and Nordic Semi nRF52840 devkit, I had not seen many Bluetooth 5 IoT modules or boards. Aconno, a German startup, has designed ACD-52832 Bluetooth 4.0 / Thread / ANT+ IoT development board based on their own nRF52832 module, and equipped with some goodies like a black & white e-Paper display, a joystick, sensors, I/Os, etc… They’ve also launched an updated module with Bluetooth 5 using nFR52840 SoC. I don’t have the full details about the new module, but the nRF52832 module and devkit is interesting to look at, especially features should be similar. Aconno ACD-52832 board specifications: Wireless Module – ACN52832 based on Nordic Semi nRF52832 ARM Cortex-M4 @ 64 MHz SoC with Bluetooth Smart, ANT+, Thread, NFC, and 2.4 GHz […]
