The DIY Walky Talky board is basically the same minus all parts related to LoRa messaging (LoRa module, keyboard, and display). The MessengerPi and DIY Walky Talky boards would mostly be useful for outdoor communications when hiking, farming, boating, etc… outside the range of any cellular networks, but SB Components won’t provide an enclosure, so you’d better hope it won’t rain, or keep the board in your RV, tractor, or boat… With a real appetite among councils and housing associations to make their homes cheaper to heat and warmer to live in, this investment is putting the power in the hands of the people who know their communities best, allowing the right decisions to be made for each home they manage while ensuring the very best for their tenants and the environment.
W25Q16JV Datasheet http://wiki.amperka.ru/_media/products:raspberry-pi-pico:w25q16jvuxiq-datasheet.pdf The RP2040-Zero board comes with or without pre-soldered pin headers (the pre-soldered version may cost a bit more). The castellated printed circuit board allows soldering direct to SMD carrier boards, while the USB-C connector keeps it up to date and easier to use. This is not a breadboard-friendly microcontroller module.

As you might have noticed, GP25 of the Raspberry Pi Pico is routed to an onboard green LED. The RP2040-Zero did not have a similar LED on board (GP25 was thus freed) but its GP16 is hardwired to the DI (data input) of the integrated WS2812 LED. Let me remind you again, you don’t need to unplug the RP2040-Zero from your computer’s USB port to reset it. Simply push and hold the reset button, press the boot button, release the reset button, and then release the boot button. Your RP2040-Zero will reconnect as a USB mass storage device.
MicroPython comes with a lot of built-in support for simple devices and communication protocols to start some fun experiments. But there are also a lot of things available for fiddling with more complex hardware. So, if you’re looking for something more advanced to do, go to the various tutorials available across the web.This technical assistance is being delivered by the Greater London Authority under the name of the Social Housing Retrofit Accelerator ( SHRA) which is available to all registered providers of social housing across England who intend to apply to the SHDF Wave 1 competition. As usual, the company does not provide any details or source code about the firmware during the crowdfunding campaign, so you have to trust them and cannot evaluate the software support before pledging your hard-earned money. They typically release libraries and sample code on their GitHub account but only have funding received. In the meantime, you can still watch a promotion and demo video below. This comes as emissions from domestic properties currently account for around 20% of the UK’s carbon output. Taken together the funding will ensure that the government is achieving its aspiration to ensure as many homes as possible reach EPC Band C or above by 2035 in a way that is practical, cost effective, and affordable. The company actually provides two boards: the MessengerPi itself for both calls and messaging with a keyboard, and the smaller “ Walky Talky” board for audio communication only and without a LoRa module.
RP2040-Zero, A Low-Cost, High-Performance Pico-Like MCU Board Based On Raspberry Pi Microcontroller RP2040, with the following key features: Today’s announcement is the latest step in the government’s plan to reduce emissions from social homes, a priority area for the government to help eradicate fuel poverty and reach net zero carbon emissions by 2050.Mrs Vivienne Challice is an example of the tenant that social housing providers will be able to help through this scheme. SB Components MessengerPi is a DIY messenger and walkie-talkie based on a Raspberry Pi RP2040 that relies on LoRa communication for P2P messaging over distances of up to 5 kilometers and calls up to 300 meters away. In the RP2040 SoC, we have two cores (0 and 1). They both share the same memory that they can communicate with. In single core operation, core 0 executes all the code you have written, while in a multicore program, core 0 starts, then hands a series of executable functions to core 1 to process in parallel.
