LiPo battery powered Olimex boards use ESP32-S2’s USB OTG interface

Olimex ESP32-S2 LiPo USB Boards

Last year, Olimex introduced ESP32-S2-DevKit-LiPo and ESP32-S2-WROVER-Devkit-LiPo boards optimized for battery-powered applications with as little as 30uA deep sleep power consumption. ESP32-S2 processor comes with a USB OTG interface, but at the time, Espressif Systems ESF-IDF SDK did not support programming via the built-in USB interface, so Olimex added CH340T USB to serial converter for programming. The good news is that the SDK can now support USB programming without an external chip, so the company designed new versions of the boards without a USB to serial chip with namely ESP32-S2-DevKit-LiPo-USB and ESP32-S2-WROVER-Devkit-LiPo-USB boards. The specifications are basically the same as previously except for the removal of the USB to serial chip, support for USB OTG, and even lower power consumption: Wireless module: ESP32-S2-DevKit-LiPo – ESP32-S2-WROOM with Espressif ESP32-S2 single-core 32-bit LX7 microprocessor up to 240 MHz with  128 KB ROM, 320 KB SRAM, 16 KB SRAM in RTC, 4MB SPI […]

Feather compatible shield Integrates BG96 Module with LTE Cat-M1, NB-IoT, and GPS

qTop BG96 FeatherWing

Last week, I wrote about the Pebble Board, an nRF9160 based LTE-M and NB-IoT GPS tracker board that connects with Thingsboard. I was soon informed about a similar solution based on Quectel BG96 and compatible with the Feather form factor. Meet IoT-Bots.com’s qTop  Adafruit Feather Compatible shield. In case you wonder, why they did not call it a FeatherWing, that’s because as it’s slightly larger, and the boards are “Adafruit Feather Compatible (AFC) from the interface connection perspective only.” Key features and specifications: Wireless module – Quectel BG96 Cellular – LTE Cat M1, NB-IoT, and EGPRS module offering maximum data rates of 375 kbps downlink and uplink GNSS – GPS, GLONASS, BeiDou/Compass, Galileo, QZSS Nano SIM card holder and u.FL connector (3) for cellular connectivity u.FL connector (4) for GNSS Expansion Feather expansion connector (11) 6-pin qJam interface connector (12) with I2C for extra sensors Misc – Network status LED, […]

CN0549 CBM development kit monitors assets through vibration analysis

CN0549 CBM Development Kit interfaced with SMA Connector

Condition Based Monitoring (CBM) has become quite popular in the manufacturing sector due to its advantages. It is a type of pre-analysis monitoring that includes the use of sensors to evaluate the status of an asset over time while it is in operation. Hence, the data collected is used to establish trends, predict failure, and measure the life of an asset. Analog Devices has launched CN0549, a condition-based monitoring development kit. The monitoring functionality signifies the consideration for hardware applications involving vibration. The applications include industrial as well as IoT devices. Hence, the CN0549 CBM development board combines the resources for a dynamic domain of users. Discussing further, condition-based monitoring (CBM) through vibration sensing requires the capturing of full-bandwidth data to ensure that all harmonics, aliasing, and other mechanical interactions are taken care of in both, the time and frequency domain. The data collection by using the sensors and data […]
