ESP8285 WiFi DIP module replaces ATMega328P MCU on Arduino UNO board (Crowdfunding)

Released over 10 years ago, Arduino UNO is still the best-selling Arduino board, but lacking WiFi in the IoT era is not ideal, so Gianluca Martino, Arduino co-founder and working with the company until 2015, decided to design the Jolly DIP module based on ESP8285 WiFi chip that can replace the ATmega328P 8-bit AVR DIP-40 microcontroller. Since ESP8285 cannot provide all I/Os, notably analog inputs offered by ATmega328P, Gianluca combined it with the ATMega328PB microcontroller in a compact SMD package to offer firmware compatibility plus WiFi connectivity in the same DIP form factor. Jolly module specifications: MCU – Microchip ATMega328PB 8-bit AVR microcontroller with 32 KB ISP Flash, 1 KB EEPROM, 2 KB SRAM (Based on data from the datasheet) Wireless chip – Espressif Systems ESP8285H16 WiFi SoC with 2MB integrated flash plus ceramic antenna Communication interfaces between the two chips – SPI + UART (the latter exclusively for ESP8285 […]

Renesas introduces RZ/Five Linux-capable 64-bit RISC-V microprocessor family

Renesas has launched its first RISC-V processor family with the RZ/Five general-purpose microprocessors based on an Andes AX45MP 64-Bit RISC-V CPU core, and with long-term Linux support via the industrial-grade CIP Linux that offers maintenance for over 10 years. The RISC-V processor is pin-to-pin compatible with the Arm Cortex-A55/M33–based RZ/G2UL processor family, and while being a general-purpose family, the RZ/Five chips are specifically well-suited to IoT endpoint devices such as gateways for solar inverters or home security systems. Renesas RZ/Five key features and specifications: CPU – Single-core 64-bit RISC-V AX45MP core @ up to 1.0 GHz Internal Memory – 128KB SRAM with ECC Memory I/F – 16-bit DDR4-1600 or DDR3L-1333 memory interfaces with in-line ECC; up to 4GB RAM Storage I/F – 2x SD/eMMC interfaces, SPI flash interface Networking – 2x Gigabit Ethernet MAC USB – 2x USB 2.0 Audio – 4-channel serial sound interface (SSI) Serial – 2x CAN/CAN-FD […]

M5Stamp C3U IoT module relies on ESP32-C3’s own USB interface for firmware programming

M5Stamp C3U is an update of the M5Stamp C3 RISC-V IoT module with heat-resistant cover, support for WiFi 4 and Bluetooth 5.0, that does without CH9102 USB to TTL chip, relying instead on the internal USB interface of ESP32-C3 processor to handle serial programming of the firmware, and gaining on extra GPIO pin in the process. While several ESP32 processors come with a built-in USB interface, many boards still use an external USB to TTL chip such as CH340 or CP2102 to handle the serial interface used for debugging and flashing the firmware likely because of limitations when using ESP32-C3’s USB serial/JTAG controller console, but M5Stack probably considered those to be workable, and the small cost-saving beneficial. M5Stamp C3U specifications: WiSoC – ESP32-C3FH4 32-bit single-core RISC-V processor @ up to 160 MHz, with 384KB ROM, 400KB SRAM, 8KB RTC SRAM, 4MB embedded flash, WiFi and Bluetooth Connectivity 2.4 GHz WiFi […]

Low-power satellite IoT SoC works with Totum’s Low Earth Orbit (LEO) network

Orca Systems ORC3990 is a low-power satellite Internet of Things (IoT) SoC that works with Totum’s Low Earth Orbit (LEO) network of satellites and targets outdoor and indoor tracking and monitoring applications. It’s not the first time we read about satellites being used for LPWAN networks, as Sigfox launched LEO satellites a few years ago to provide worldwide coverage even in remote locations like the Sahara desert, the two poles, and oceans. But I had never heard of Totum or Orca Systems before, so let’s have a closer look. Orca Systems ORC3990 ORC3990 specifications: Unnamed Arm cores Integrated RF Transceiver Low Power Sensor-to-Satellite (LP-S2S) connectivity in the 2.4 GHz ISM band Totum DMSS modem for improved doppler performance Link budget enables indoor signal coverage Support location fixes with 20m accuracy Low power – 10+ year battery life Package – 7x7mm QFN chip Temperature Range – -40 – +85°C Process – […]

IoT device monitoring as a product reliability improvement tool

IoT Device Monitoring with Torizon Platform

CNXSoft: This is a guest post by Renato Kiss, Product Manager – Software at Toradex, explaining how IoT device monitoring can be used with open-source software tools like Fluent Bit to improve product reliability, using temperature monitoring as an example. It is impossible to dissociate connected devices from modern life. They are present in homes, offices, industries – basically, in every business, connected devices play vital roles. In a market estimated at 24.1 billion devices and with a revenue of more than USD 1.5 trillion by 2030, IoT will grow based on both consumer and business applications. Hardware will account for about one-third of this value with the majority being distributed in services, including the connectivity for the system. As part of this growth, more services will be added to IoT business and some specialists estimate the economic potential, including IoT products and services, can unlock at least USD 5.5 […]

Ai-Thinker BW16 is a dual-band WiFi & Bluetooth 5.0 IoT module (Sponsored)

Ai Thinker BW16 dual-band WiFi BLE 5.0 module

Many users prefer the ESP32 when implementing WiFi & Bluetooth into their IoT projects. But Ai-Thinker BW16 offers dual-band WiFi 4 & Bluetooth 5.0 connectivity through Realtek’s RTL8720DN chipset which may provide more reliable connectivity where the 2.4 GHz band is crowded. The module integrates an Arm Cortex-M4F compatible high-performance MCU, an Arm Cortex-M0 compatible low power MCU, WiFI 802.11 a/b/g/n, MAC, Bluetooth and RF baseband, and provides a set of configurable GPIO ports to control peripheral devices. BW16 module One significant difference between BW16 and ESP32 module is that it has two serial port interfaces, so attention should be paid to the wiring of the UART interfaces. The following diagram shows the two serial interfaces of the BW16 module. One of the module serial interfaces is used to send and receive AT commands to control connectivity from a host processor or microcontroller, while the other serial port is used […]
