Espressif “Chip 7” WiSoC May Support 5GHz WiFi

Espressif Chip 7

Espressif Systems has not released any new chips since the launch of ESP32 WiFi & Bluetooth SoC in 2016. But it looks like an new chip may be right around the corner, as John Lee from Espressif Systems teased us with a photo featuring a module equipped with “Chip 7” that should be released “soonish”. We really don’t know much about the chip except it comes in a 56-pin QFN package (4x 14 pins), and it won’t most likely be named Chip 7 once it is released. One Twitter user left a comment mentioning that it “looks like a bodged RF Filter. 5GHz mod?”. This reminded me of the potential ESP32-D0CD / ESP32-D2CD processors with dual band (2.4 + 5 GHz) WiFi. When I say “potential” it simply refer to the fact that ESP32 nomenclature has a “CD” connectivity option for WiFi ac/c/b/g/n and Bluetooth dual mode. But Espressif never officially announced anything about ESP32-D0CD yet, and ESP32 chips are …

Getting Started with Temperature & Humidity Sensors on ESP8266 using ANAVI Thermometer

ANAVI Thermometer Air / Humidity / Water

ANAVI Thermometer was launched on CrowdSupply in January.¬† It is an ESP8266 WiFi board with a built-in DHT22 temperature and humidity sensor, support for external DS18B20 waterproof temperature sensor, as well as other sensors thanks to three I2C sensors. I received the ANAVI Thermometer starter kit last month, and I’ve only found time to play with it in the last few days. I’ll start with a unboxing, assembly guide, before showing it action, and I’ll try to make it interface with Home Assistant over MQTT. ANAVI Thermometer Starter Kit Unboxing The kit comes with ANAVI Thermometer board, a plastic stand, a USB to TTL debug board, an I2C OLED display, a few nuts and bolts, and a couple of KiCad and ANAVI stickers. Leon ANAVI also added a traffic light board and LEDs, but it’s not normally part of the kit ūüôā ANAVI Thermometer board include an ESP8266 module, AM2302 (wired DHT 22) temperature and humidity sensor, a terminal block …

FOSSASIA 2019 Schedule – March 14-17

FOSSASIA 2019 Schedule

As its name implies, FOSSASIA is a Free and Open Source Software¬† event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event.¬† Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have the potential to grant bad actors access to your screen …

The Things Industries Announces $69 Indoor Multi-Channel LoRaWAN Gateway

Indoor Multi-channel LoRaWAN Gateway

If you ever see a cheap LoRaWAN gateway, chances are that it is a single channel gateway such as Dragino LoRa gateways that can be purchased for as low as $56. Those will work for your private network, but if others people try to use your gateway, some LoRa nodes will fail to connect. So what you really need is a multi-channel gateway for instance to connect it to The Things Networks. That would be $200 (and up), thank you very much. The IoT can only succeed on a large scale if costs are low enough, so Things Industries decided to design, and has now unveiled a low cost indoor multi-channel LoRaWAN gateway. Meet The Things Indoor Gateway. The Things Indoor Gateway specifications: SoC – Espressif System ESP8266 WiSoC Wireless Connectivity 802.11 b/g/n WiFi 4 via ESP8266 + PCB antenna LoRaWAN via Semtech 1308 chipset with Support for 868 MHz (EU) and 915 MHz (US) bands. AS bands coming later …

ESP32 CoinCell is a Tiny, Coin Cell Powered ESP32 Pico D4 Board

ESP32 CoinCell

ESP32 boards can easily be powered by batteries, either through an external USB battery shield, or direct connection to an ESP32 board fitted with battery charger circuitry. But Miek Rankin has done something a bit different, as he designed ESP32 Coincell board based on an ESP32 Pico D4 SiP (System-in-Package) powered by a¬†rechargeable LIR2450 coin cell battery with 100mAh capacity. ESP32 CoinCell board specifications: SiP – Espressif Systems ESP32 Pico D4 Wifi/Bluetooth processor Connectivity 802.11 b/g/n WiFi up to 150 Mbps Bluetooth 4.1 LE On-board antenna Display – 0.69″ OLED display with 96×16 resolution USB – 1x micro USB port for charging and debugging (via CP2102N USB to TTL chip) Sensor – LIS3DHTR accelerometer Battery / Power Supply SE5218ALG-LF 500mA LDO power supply SL4054ST25P LiPo battery charger Socket for¬† for LIR2450 (3.7V/100Mah battery) Consumption – 0.45mA in sleep mode Dimensions – Small If you don’t connect the battery, the board can still be powered through the USB port. No battery …
