Nit841-v3

Kingswood.
2
layer board of
1.36x1.36
inches

mm).

NRF24 nitwork node with ATTiny841, LM92 or DS1621 temperature sensor, 3.3V regulator. It uses ISPogo landing pads for in-system programming.
V3 has improved layout giving 50 uncommitted pads on a 0.1" grid for experimentation and expansion.
The board has space for a CR2032 battery on the bottom. Power consumption is under 1mA when the radio is off.
This board is designed to fit in a Hammond 1551P case, 40x40x20mm. The NRF24 only fits in the box if it is soldered down directly, but using the header and a socket works fine outside this box.
