AdaFruit, Seeed, SparkFun, DFRobot, DigiKey
Over at Seeed Studio they have the Particle P1 WiFi module running the BCM43362 IC and an STM32F205 with 1MB flash, external 1MB SPI flash and 25 GPIOs.
This one has a break-away antenna or there’s the smaller Particle P0 module.
The BlueStack Micro+ is another DVMEGA board that supports DMR over Bluetooth or DSTAR, Fusion and DMR over USB. This one is designed specifically for the IoS platform, and this one for the Android platform.
Over at AdaFruit they have a FeatherWing with on-board INA219 IC, which is a power monitor allowing you to measure up to 3.2A and 26V DC. You can change the current sense resistor to a lower value to increase the max amperage to 32A.
Over at SparkFun they have a spectral sensor. No, not a spectre sensor. It’s not Halloween yet! It’s a spectrometer that will detect wavelengths from 450 to 650nm in the visible spectrum. Accessible over I2C and UART.
They also have one that extends that range from 610 to 860nm.
Back in Weekly Roundup #34 we saw the qualMeter on Kickstarter. Well now DFRobot are selling all three models; the Advanced, Mini and <a href=”https://www.dfrobot.com/product-1640.html?tracking=5987cead3290e”>Basic.
And LED panels are getting cheaper and cheaper. Unfortunately I missed out on the used 64 by 64 panels on eBay at a ridiculous price, but DFRobot have them still.
Over at DigiKey they have some tiny power modules based on the TPSM842 giving you 3.3, 5 or 12v out from a 24v input. Pretty handy.
