So over on this facet of the pond (UK) $1.60 wouldn’t purchase you a stamp to ship a letter, and it actually wouldn’t get you far on public transport or a lot of a meal. It’s fairly astonishing nevertheless what it should purchase you in electronics phrases. Take for instance this Bluetooth BLE Serial UART module!

Whereas I’m unsure what the “Genetical” a part of its title means, it seems to be like an enormous quantity of expertise in a tiny package deal for little or no coin. Primarily based on the RF-Star RS02A1-B system on chip, it needs to be fairly succesful as this can be a 32-bit ARM Cortex-M0+ gadget clocked at 48MHz.

It gives low energy consumption whereas promising first rate transmission distance. There’s onboard energy and RF filtering to hopefully scale back noise and there’s a alternative of utilizing both the onboard PCB antenna or utilizing the IPEX connector so as to add your personal exterior antenna.

Supporting the BLE V5.0 stack, the gadget has 2 UART interfaces in addition to I2C. There are additionally 11 configurable general-purpose IO pins. It’s price trying over the product web page for the frankly astonishing quantity of stuff this gadget has, IR, DMA, Quadrature encoding… the record goes on.

It comes totally assembled with a castellated header; it could be fairly simple to combine this with pin headers or to design customized PCB footprints. It’s numerous energy packed right into a tiny package deal!
